Prefix-1 ESC The next character typed will be interpreted on the basis that it was preceded by the command Prefix-1. This is one of two such commands whose purpose in life is to increase the number of com- mands that can be bound to keys and thus easily invoked. Prefix-2 ^X The next character typed will be interpreted on the basis that it was preceded by the command Prefix-2. This is one of two such commands whose purpose in life is to increase the number of com- mands that can be bound to keys and thus easily invoked. append-region [unbound] Appends the region bounded by the point and mark to the named file. If the file does not exist it is created. apropos(keyword) ESC-? Lists available commands having to do with the keyword. backward-character ^B Moves the point backward one character in the buffer. If the point is at the beginning of the line, it moves it to the end of the previous line. backward-paren ESC-^B This moves the point to the matching open parenthesis (brace) of the close parenthesis (brace) just before the point. If there is no match, an error is reported and the point remains unchanged. backward-word ESC-B If in the middle of a word, the point moves to the beginning of the word. Otherwise it moves the point to the beginning of the previous word. beginning-of-file ESC-< Moves the point to the beginning of the current buffer so that the character after the point is the first character of the buffer. beginning-of-line ^A Moves the point to the beginning of the current line. beginning-of-sentence ESC-A Moves the point to the beginning of the current sentence. beginning-of-window ESC-, Moves the point to the first character in the window. bind-macro-to-key [unbound] Binds a macro to a key so that future hits on that key will run the macro. bind-to-key [unbound] Binds a command to a key so that future hits on that key will run the command. For example, the command next-line is bound to the key ^N. buffer-position [unbound] Prints the line and column of the point in the current buffer. case-region-lower ^X-^L Changes all the letters between the point and mark to lower case. case-region-upper ^X-^U Changes all the letters between the point and mark to upper case. case-word-capitalize ESC-C If the point is in the middle of a word, it capitalizes the letter after the point and changes the rest of the word to lower case. Otherwise it capitalizes the first letter of the next word and changes the rest of this word to lower case. In any case the point is left at the end of the word. case-word-lower ESC-L If the point is in the middle of a word, it changes the rest of the word to lower case. Otherwise it changes the next word to lower case. In either case the point is left at the end of the effected word. case-word-upper ESC-U If the point is in the middle of a word, it changes the rest of the word to upper case. Otherwise it changes the next word to upper case. In either case the point is left at the end of the effected word. char-to-octal-insert [unbound] Reads a character from the terminal and inserts its octal value preceded by a back-slash '\', into the text at the point. For example if the character ESC is typed, the string \033 is insert- ed. clear-and-redraw ESC-^L Clears and redraws the screen without changing the screen orien- tation. This is useful if the screen gets garbaged by output from another program or by someone writing you. compile-it ^X-^E Writes all the modified buffers and runs the UNIX program make into a buffer called Errors. After the make is completed, the buffer is parsed for C type error messages to be used by the next-error command. copy-region ESC-W Does a pretend kill of the region bounded by the point and mark. The next call to yank will yank the region just copied. c-tab [unbound] When in c-mode, the command c-tab is automatically bound to the tab key, and when invoked, the point is tabbed to the "right" place for C programs. delete-next-char ^D The character after the point is deleted moving the rest of the line to the left one, leaving the point unchanged. If at the end of the line, the line boundary is deleted joining the current line with the next line. delete-next-word ESC-D If the point is in the middle of a word, it deletes to the end of the word. Otherwise it deletes the entire next word. In either case, the point doesn't move, and the deleted text is saved in the kill buffer. delete-other-windows ^X-1 Makes the current window the only window by deleting all the oth- er windows. The window grows to fill the screen as it is when the editor starts up. delete-previous-char DELETE Deletes the character before the point moving the rest of the line to the left one. If the point is at the beginning of a line, the previous line is joined with the current line and the point is moved to what used to be the end of the previous line. delete-previous-word ESC-DELETE If the point is in the middle of a word, it deletes to the begin- ning of that word. Otherwise it deletes the entire previous word. In either case, the deleted text is saved in the kill buffer. delete-to-killbuffer ^W Deletes all the text between the point and mark, saving it in the kill-buffer. This is one of the the ways to move text from place in the buffer to another. The yank command will insert the most recently deleted text at the point. Jove remembers 10 separate kills in a kill ring. The yank-pop command can be used to go through the ring one at a time. delete-white-space ESC-\f1 Deletes all tabs and space around the point on the current line. This does not work over line boundaries. describe-command [unbound] Prompts for the name of a command and describes what the command does into a buffer. describe-key ^X-^D Prompts for a key and prints the command that is bound to that key. delete-current-window ^X-D If there is more than one window on the screen, the current win- dow is deleted and is moved to neighboring window. The space from the deleted window is given to the new current window. end-of-file ESC-> Moves the point to the end of the buffer making the character be- fore the point the last character in the buffer. end-of-line ^E Moves the point to the end of the current line. end-of-sentence ESC-E Moves the point to the end of the sentence. end-of-window ESC-. Moves the point to the last character in the window. erase-buffer [unbound] Prompts for a buffer name, and deletes all the text in that buffer. If the buffer is modified, the user is asked for confir- mation. exchange-point-and-mark ^X-^X Sets the mark to the point and the point to the mark. execute-extended-command ESC-X Prompts for a command to run using command completion. This is how all commands would be run if not for the bind-to-key command. execute-keyboard-macro ^X-E All the characters that were remembered with the start- remembering command are executed as if they were typed at the keyboard. execute-macro [unbound] This is the same as execute-keyboard-macro except that it prompts for the name of a macro to execute. exit-jove ^X-^C Exits jove. It asks for confirmation if there are any modified buffers which have not been saved. filter-region [unbound] Prompts for a UNIX command to send a region to. The region will be replaced with the output from the command. For example to format a C procedure, a region around the procedure should be de- fined and the filter-region command used to send the region through the UNIX C beautifier. find-file ^X-^F Prompts for a file to find. If that file is not already in a buffer, it creates a new buffer and reads the file into that buffer. If the file is already in another buffer, that buffer will be selected instead. In any event the current buffer be- comes buffer with that file in it. find-file-into-other-window ^X-4 Do a find file into another window. If there is only one window, is split. If there is more than one window, one of the windows that is not the current window is used instead. find-tag ^X-^T Finds the file with the C tag which is prompted for. The UNIX program ctags(1) should be used to create a database with the necessary information to find the file which contains the tag. If the tag cannot be found, the point and buffer are unchanged. first-non-blank ESC-M Moves the point to the first non blank character in the current line. forward-char ^F Moves the point forward one character in the buffer. If at the end of the current line the point is moved to the beginning of the next line. forward-paren ESC-^B Moves the point to the matching close parenthesis (brace) of the open parenthesis (brace) right after the point. If there is no match, an error is reported and the point remains unchanged. forward-word ESC-F If the point is in the middle of a word, it moves to the end of the current word. Otherwise it moves to the end of the next word. four-times ^U Multiple the numeric argument by four. The sequence ^U-^U-^N runs the command next-line 16 times. goto-line ESC-G Moves the point to the numeric argument line in the buffer. If no argument is supplied, the the point moves to the first line in the buffer. grow-window ^X-^ Makes the current window one line larger if it can. There has to be more than one window, and the window which would get smaller has to be big enough to get smaller. i-search-forward [unbound] Incremental search forward. See the EMACS Manual for TWENEX Users if you care about this command. I do not have time to ex- plain it right now. i-search-reverse [unbound] Incremental search reverse. See the EMACS Manual for TWENEX Users if you care about this command. I do not have time to ex- plain it right now. insert-file ^X-^I If the named file exists and can be read, its contents are in- serted into the current buffer at the point. Otherwise an error is reported and the point is unchanged. init-bindings [unbound] Initialize the bindings to the way they were at the beginning of the edit. justify-paragraph ESC-J Justifys a paragraph. Paragraphs are bounded by blank lines or lines that begin with a period. The margin-length variable determines the length of each line in the paragraph. kill-buffer ^X-K Deletes a named buffer. This command is not reversible; once the buffer is deleted, it is gone forever. It is useful when the ed- itor runs out of space and there is a buffer which you do not care about. kill-to-end-of-line ^K Kill all the text from the point to the end of the line. If the point is at the end of the line, the current line is joined with the next line. If a numeric count is given, the next count lines are deleted. The saved test can be yanked back with the yank command (see delete-to-killbuffer). If this command is run several times in a row all the kills are merged into the same kill ring entry, thus running the yank command will yank all of them back instead of just the last one. list-buffers ^X-^B Creates a buffer called Buffer list that contains a list of all the buffers jove currently knows about. Each line tells each buffer's number, type, file associated with it, its name, and a * if the buffer is modified. make-buffer-unmodified ESC-~ Makes the editor forget that the buffer has been modified. The * on the mode line will disappear if it is there. name-keyboard-macro [unbound] A new macro is defined with the name supplied by the user. The current definition of the keyboard macro is copied into this new macro, making it possible change the keyboard macro without los- ing the old version. Now it is possible to run the new macro by binding the macro to a key, or with the execute-macro command. Note that only named macros are saved with the write-macros-to- file command, so to remember macros from one jove to another, one must give the macro a name, execute the write-macros-to-file com- mand, and upon invokation of a new jove, the read-macros-from- file" command should be executed. newline [unbound] Divides the current line at the point moving the point to the be- ginning of the newly created line. It is usually bound to the return key. newline-and-backup ^O Divides the current line at the point like the newline command, but leaves the point unchanged. newline-and-indent [unbound] Same as newline except that it inserts white space at the begin- ning of the newline copying the indent of the previous line. next-error ^X-^N Takes the next error message (as returned by the parse commands), finds the file in which the error occurred, and sets the the point to the line on which the error occurred. The error message will be displayed at the top of the errors buffer. (The compile-it command automatically runs the parse-C-errors and the next-error commands). next-line ^N Moves the point to the next line keeping the column as close to the current column as possible. next-page ^V Puts the bottom line of the window at the top of the window, mov- ing the point to the top of the window and to the beginning of the line. next-window ^X-N Moves to the next window in the screen. If the current window is the last window, it moves to the first window. It is an error to move to the next window when there is only one window on the screen. number-lines-in-window [unbound] Each line in the current window is displayed with its line number to the left. The number isn't part of the buffer and will disap- pear when this command is executed again (it toggles). page-next-window ESC-^V This command does a next-page on the next window. If there is only one window the editor complains. paren-flash [unbound] When the variable show-match is non-zero, the close parenthesis/brace keys are bound to this command. When invoked, this command inserts the character typed and temporarily flashes to the matching open parenthesis/brace for about one second. parse-C-errors [unbound] This command takes C compiler (or similar in format) errors and sets the editor up for subsequent invocations of the next-error command. Giving the UNIX command grep(1) the -n option prints the output in the same format as the C compiler, thus running this command into a buffer makes it possible to parse its output. This is a very useful way to look at all the occurrences of cer- tain strings in several files. parse-LINT-errors [unbound] This is the same as parse-C-errors excepts parses lint errors. pause-jove [unbound] If the system has the Berkeley job control features, control is returned to the superior shell. Otherwise an inferior shell is spawned. previous-line ^P Moves the point to the previous line trying to keep the column the same. previous-page ESC-V Moves the top line in the window to the bottom line leaving, the point at the top of the window and at the beginning of the line. previous-window ^X-P Move to the previous window in the screen. If currently in the first window, moves to the last window. It is an error to move to the previous window when there is only one window on the screen. print [unbound] Prompts for a variable name and prints its value. query-replace-search ESC-Q Upon receipt of a search and replacement string, the editor re- places all occurrences of the search string with the replacement string. For each occurrence the editor asks the user what to do. The choices are: ' ' to replace this occurrence. '.'to replace and stop. DELETE to skip this occurrence. 'r' to recursive edit. 'p' to proceed to replace all occurrences. RETURN to stop When there are no more occurrences, the point is moves back to its initial position. Recursive edit makes it possible to tem- porarily suspend the query-replace-search, let the user go off and do some editing, and then return to the search after the editing is finished. Executing the command exit-jove returns from the recursive edit. quote-char ^Q Quotes the next character typed for insertion. This is used to insert special characters which normally would be interpreted as commands. read-file ^X-^R Prompts for a file to read into the current buffer. It will erase the old contents so if the buffer has been modified, but not saved, jove complains and ask for confirmation. read-macros-from-file [unbound] Prompts for a file that was previously written with the write- macros-to-file command, and reads them back into the editor. redraw-display ^L Redraws the window with the current line in the middle. If a numeric argument is provided the current line is moved to the ar- gument line. If the current line is in the same place as before, the window is cleared and redrawn. reinitialize-terminal If the value of the variable allow-^S-and-^Q is changed, this command should be called to make the necessary changes to the terminal. replace-search ESC-R This is the same as query-replace-search except the editor does not ask whether to replace it; it always does. ring-the-bell ^G Exactly what is says. Its useful when it is not apparent what the editor is currently doing. scroll-one-line-down ESC-Z Scrolls the current window down one line. If the current line moves off the bottom of the window, it is moved to the middle of the window. scroll-one-line-up ^Z Scrolls the current window up one line. If the current line moves off the bottom of the window, it is moved to the middle of the window. search-forward ^S Prompts for a string to search for and searches for the next in- stance of that string in the buffer (see searching above). search-reverse ^R Prompts for a string to search for and searches for the previous instance of that string in the buffer (see searching above). select-buffer ^X-B Prompts for a buffer name and makes that buffer the current buffer. If the buffer does not exist a new buffer is created with nothing in it. If a number is supplied instead of a name and a buffer exists with that number, that buffer is selected. Otherwise a new buffer is created with that number as a name. self-insert [very-bound] This is bound to all the keys that should be inserted when typed. This commands does not work unless bound to a key. Running this command manually will probably cause a random character to be in- serted. set [unbound] Prompts for a variable name and a value, and sets the variable to that value. set-mark ^@ Sets mark to the current buffer location. shell-command ^X-! Prompts for a UNIX shell command to be run placing the output from the command into a buffer called Command execution. If the a numeric argument is provided, the buffer is left alone before the UNIX command is started. Otherwise the buffer is emptied. shell-command-to-buffer [unbound] The same as shell-command except that it asks for a specific buffer to place the output in instead of Command execution. source [unbound] This prompts for a file name which contains a bunch of editor commands. These commands typically set variables or bind com- mands to keys. Running source on a file which does not have edi- tor commands in it will likely cause the editor to crash. This is a serious bug. shrink-window ^X-Z Shrink the current window by one line if the resulting window would not be too small. It is an error to run this command when there is only one window. spell-buffer [unbound] Sends the entire buffer to the UNIX spell program. Jove will go through the list of spelling errors and asks whether or not a word is spelled correctly. If it is not, jove remembers where each occurrence of the misspelled word is. The point in the buffer being spelled is positioned at the end of the current misspelled word. The next-error command moves to the next oc- currence of the current word, or to the first occurrence of the next word. split-current-window ^X-2 Splits the current window into two smaller windows, if the resulting windows would not be too small. The two windows have the same buffer associated with them, namely the one that the original window had. start-remembering ^X-( This tells jove to start remembering all the following keystrokes until the stop-remembering command is executed. The saved com- mands are saved in the keyboard macro, and can be re-executed with the execute-keyboard-macro command. This is useful when it is necessary to run the same command lots of times. stop-remembering ^X-) This terminates the definition of a macro. See start-remembering for more details. string-length ^X-C Prints, on the message line, the number of characters between two quotes. The point must be between two quotes or the editor com- plains. This is useful for C programmers especially. suspend-jove [unbound] Same as pause-jove. text-insert [unbound] When the variable text-fill is non-zero, the self-insert keys are bound to this command. This inserts characters like self-insert does but when the line gets to a certain length, a newline is au- tomatically inserted. This makes it possible to type in a paper without having to remember to hit return, i.e the editor does it automatically. transpose-char ^T Switches the characters on opposite sides of the point, namely the character before the cursor and the character under the cur- sor. unbound [unbound] The unbound function is bound to all the keys that don't run com- mands. It is essentially a no-op. visit-file ^X-^V Same as the sequence split-current-window followed by executing find-file. vt100-arrow-keys [unbound] This makes the arrow keys work on the vt100 terminal. write-current-file ^X-^S This writes the current buffer to the file associated with the buffer, without asking. If there is currently no file associated with the buffer, the editor complains. (See the write-named-file command below). write-macros-to-file [unbound] Prompts for a file and writes all the current defined macros to that file. The macros can be read back into the editor with the read-macros-from-file command. write-modified-files ^X-^M Writes all the buffers that have been modified but not been saved. write-named-file ^X-^W Prompts for a file name and writes the current buffer to that file. If the file already exists and is not the current file name, the user is informed and asked if he really wants to do it. Writing a file erases the old contents of the file. write-region [unbound] Takes the region between the point and the mark and writes it to a named file. yank ^Y Inserts, at the point, all the text that was most recently delet- ed with a delete command that saves the text it deleted to the kill ring. The point moves to the end of the inserted region. yank-pop ESC-Y Goes through the kill ring inserting each entry one at a time. The previous command has to have been the yank command or the yank-pop command.
