Wright All rights reserved Appendix notes ====================================================================== APPENDIX CONTENTS ====================================================================== 1.) Text Editing Windows (defaults, inheritance, and more) 2.) QED Requesters (special features, short cuts, etc.) 3.) QED and the clipboard.device (special notes, unit #'s, etc.) 4.) Exporting text (things to be aware of) 5.) Entering binary characters (how to do this) 6.) Block & Column marking (special notes) 7.) Default key mapping (a table of information) 8.) Notes on 2.0 compatability (information) *** SPECIAL NOTE *** There is a distinction between an Amiga process, and an Amiga task. It turns out that the terminology "task" is more common than "process". For this reason the following documentation may use the former terminology; it is assumed that those who understand the distinction also understand the former terminology. ====================================================================== QED TEXT EDITING WINDOWS ====================================================================== QED allows you to work with multiple files, and text editing buffers in the form of multiple text editing windows. There is no significant performance penalty for opening multiple windows, and it is more efficient then running QED as multiple editing tasks. Each window can be set-up independently of the others, though you can share data between text editing windows by way of the clipboard.device, or intermediate files. Some things to be aware of about QED windows - Be careful not to confuse NEW windows with those opened by another QED task. Windows opened with the NEW command belong to a single QED task, and run as a single Amiga task. However you can still share data between windows opened by another QED task. NEW windows can be set-up with a variety of independent text editing options, however some options are global to a QED task. For example, the option to use the ARP file requester is global, meaning that all NEW windows opened by a QED task will be affected by this option. NEW windows will be opened with some default settings unless you change those settings manually, or by way of a macro. When you select an item from the pull-down menus, the item affects the the window from which the command was issued. The same is true of QED's command mode; commands affect only one window at a time. NEW windows inherit settings from previous windows. Window defaults, and inheritance are listed below. NEW window defaults - - A 1024 byte initial text editing buffer. - Pen color 1. - Paper color 0. - Paper/Pen color combination 1. - Border/Detail pen color combination 1. - Hard tab size of 8. - Right margin 75. - Left margin 1. - Mark block mode off. - Mark column mode off. - Visible linefeeds off. - Visible hard tabs off. - Slider gadget off. - Use character $AB for visible linefeeds. - Use character $B7 for visible hard tabs. - Text editing is allowed. - Preserve marked block off. - Bookmark position is line 1, column 1. - No path, or file name. - Single, and double mouse clicks are handled in the default manner. - Horizontal scrolling is set to even multiples of 8 characters. - Overstrike mode off. - Word wrap on. - Margin lock off. - Auto Indent off. - Block line mode off. - Free cursor movement on. - Tab key insert mode on. - Soft tabs off. - Append mode saves off. - Backup files off. - Create icons off if started from the CLI. - Create icons on if started from the Workbench. - Detab saves, and print OFF. - Window is opened full screen size a few pixels below the title bar. - Case sensitive searches OFF. - Forward search mode TRUE. New windows inherit these options from the previous window - - Pen, and paper colors. - Pen/Paper present combination value. - Border/Detail pen present combination value. - Visible linefeeds, and hard tab flags. - Tab size. - Margin settings. - Horizontal scroll amount. - Proportional slider gadget flag. - Character values to use for visible linefeeds, and hard tabs. - Editable flag. - Preserve marked blocks flag. - Path name. - Overstrike mode flag. - Word wrap mode flag. - Margin lock mode flag. - Auto indent mode flag - Block line mode flag. - Free cursor movement mode flag. - Tab insert mode flag. - Soft tabs mode flag. - Append mode saves flag. - Backup files mode flag. - Create icons mode flag. - Detab saves, and print mode flag. - Window is opened slightly smaller then the previous window. - Case sensitive search flag. - Forward/Backward search direction flag. ====================================================================== QED REQUESTERS ====================================================================== QED's requesters are all automatically adjusted to make use of your system font. All requesters are opened in draggable windows, so you move them out of your way, and the position where you last left them is remembered for the duration of the text editing session. QED's requesters use standard Amiga gadgets. As a reminder, you can use the mouse to position the cursor within string gadgets. You can also clear the gadget by pressing RIGHT AMIGA X, and undo any changes with RIGHT AMIGA Q. String gadgets allow you to edit the contents of the gadget using the cursor left/right keys, DELETE key, BACKSPACE key, and SHIFTED cursor keys to move to the end, or beginning of the line. Keyboard shortcuts: ----------------------------------------------------------------- Within QED, pressing RETURN within a string gadget will move the cursor to the next field, or be considered equivalent to clicking on the OK gadget. Pressing SHIFT-RETURN within a string gadget will activate the next/previous string gadget if any. If there is only one string gadget, it is deactivated. Pressing ALT-RETURN within a string gadget deactivates the string gadget. Pressing RETURN, SHIFT-RETURN, or ALT-RETURN will activate a string gadget if no string gadget is currently active. Note that if a string gadget is NOT activated, you can use the keyboard to respond to requesters. For example, press the 'o' key for OK, or the 'c' key for CANCEL. Within the Search & Replace requesters, you can use the 'a' key to toggle case sensitive search mode on/off, and the 'f', or 'b' key to toggle between forward/backward search modes. Requester types: ----------------------------------------------------------------- File requester - As of V2.0, QED uses the standard system file requester. Search - This requester is displayed when you select "Search..." from the pull-down menus. It waits for you to enter a search string, and press RETURN. You may also enter the search string, and click on the OK, or CANCEL gadgets without pressing RETURN. Two other gadgets allow you to select case-sensitive, or non case-sensitive search modes as well as forward, or backward search modes. Search & Replace - This requester is displayed when you select "Replace..." from the pull-down menus. It waits for you to enter a search string, press RETURN, then waits for you to enter the replace string. You can then press RETURN again, or click on the OK, or CANCEL gadgets without pressing RETURN. Two other gadgets allow you to select case-sensitive, or non case-sensitive search modes as well as forward, or backwards search modes. Notices - Notices are small windows displaying a one line message, and a gadget labeled OK. You can also respond to notices by pressing the 'o' key on the keyboard. Info - The ABOUT requester is an example of an INFO requester. Like notices, you can respond to INFO requesters by clicking on the OK gadget, or pressing 'o' on the keyboard. Queries - Like notices, a query requester displays a one line message, but it gives you an opportunity to respond with OK, or CANCEL. You can also respond to these requesters by pressing 'o', or 'c' on the keyboard. Numeric - Numeric requesters display a one line message, and wait for you to enter a number from the keyboard. If the string gadget is not activated, you can also respond to numeric gadgets by pressing 'o', or 'c' on the keyboard. String - String requesters display a one line message, and wait for you to enter a string of text from the keyboard. If the string gadget is not activated, you can also respond to string gadgets by pressing 'o', or 'c' on the keyboard. ====================================================================== QED AND THE CLIPBOARD.DEVICE ====================================================================== QED by default makes use of the clipboard.device to hold blocks, and columns of text which have been cut, or copied. If you are using the 2.0 clipboard.device, it is suggested you include these two lines in your startup-sequence. makedir ram:clipboards assign clips: ram:clipboards QED will not open the clipboard.device until the first time you perform an operation which needs it. Because the clipboard.device is traditionally a disk-based module (stored in the DEVS: directory), this means the first time you cut, or copy a block/column of text, you will notice that QED has to load the clipboard.device from disk. The clipboard.device will frequently save any "clips" to the CLIPS: directory, which is by default assigned to your DEVS:clipboards directory. While some people find this irritating, it does mean that blocks of text are flushed from memory regularly, and retained in the clipboard files. If you direct CLIPS: to something more permanent then RAM:, you will find your last copied, or cut block of text is still there next time you boot your machine. By default, QED uses the shared clipboard (unit 0) for blocks of text, and clipboard (unit 1) for columns of text. You can change the unit numbers used for blocks, and columns of text via QED's command mode. What this does is allow you to share blocks, and columns of text between QED task without mixing the two. In both cases the text is written to the clipboard in simple IFF TEXT format so you can shared data with other programs which use the clipboard.device. As you can change the unit numbers used by a QED task, you have the ability to share columns with other Amiga programs via the shared clipboard unit 0. The clipboard.device is also useful in an ARexx environment in which you want to share data with another program using an agreed upon set of clipboard unit number(s). Columns of text are written as lines of text terminated with LINEFEEDS, where each line is padded with trailing spaces as needed so that it can be re-inserted later retaining the columnar width of each line. However you can insert any piece of text placed in the clipboard in columnar format. If the lines have not been padded with spaces by the application writing the IFF TEXT clip, then they are inserted "as is" without regards to final appearance. In some cases this may be desirable, but in most cases it is preferable to only insert columns copied, or cut from within QED. You have the option of not using the clipboard.device in QED, in which case all blocks, and columns of text cut, copied, or pasted are managed by QED in QED's own private clipboard. Typically this option is used when you want to keep your clips private to a QED process, or if you have some personal grudge against using the Amiga clipboard.device. ====================================================================== EXPORTING TEXT ====================================================================== Text can be exported to other Amiga programs by way of the Amiga clipboard.device, or files. Amiga Compilers, the CLI batch file mechanism, ARexx, and Amiga text file readers can use files created with QED without any modifications. Most telecommunication services also send, and receive standard ASCII files, however there are three things you will want to be aware of - Hard Tabs - Not all programs are equipped to deal with hard tabs, especially re-sizeable hard tabs which requires a lot of extra logic to display properly. Many programs which do allow hard tabs in files assume correctly that hard tabs stops are set to even multiples of 8 columns. For maximum portability, you should work with hard tab stops set to even multiples of 8 columns, or you can detab your files when saving them. End of lines - Because QED is an Amiga oriented program, it uses standard Amiga linefeeds (binary 10) for end-of-line characters. You may also use binary 0's for end-of-line characters within QED; a feature which has been added for Amiga programmers. Other systems may use some other character, or characters for end-of-lines. Most common are carriage returns (binary 13), and carriage return / linefeed combinations. You can use QED's fast global search, and replace to convert between any end-of-line combinations that you want, saving intermediate files for uploading to a telecommunication service, or other system. Binary characters - Even though you can work with binary characters in QED, other programs may trip over characters outside of the standard ASCII character set. ====================================================================== ENTERING BINARY CHARACTERS ====================================================================== QED is a text editor, however you can open, insert, and save "binary" files. When QED reads files from disk, it reads the entire contents of the file into memory without stripping, or modifying anything. The same thing is true when writing files, except when you have selected to detab output. In this case all hard tabs (binary 9) would be converted to whatever number of spaces are needed. QED utilizes your system font, and it is worth noting that AMIGA fonts generally do not contain character definitions for the complete binary character set 0-255. Most system fonts only have character imagery for binary 32-255, and possibly a smaller subset of characters. Undefined characters are displayed using a default image (usually a box). In order to compensate, QED's fast text rendering routines can display the characters "@" through "_" in inverted imagery to represent binary 0-31. If you have turned the fast text rendering routines off from the command mode, then you may have to use an extended system font in order to display these characters. You can also enter these characters from the keyboard by holding down the CTRL key, and pressing the following keys on the keyboard: @ = binary 0 (CTRL SHIFTED 2) p = binary 16 a = binary 1 q = binary 17 b = binary 2 r = binary 18 c = binary 3 s = binary 19 d = binary 4 t = binary 20 e = binary 5 u = binary 21 f = binary 6 v = binary 22 g = binary 7 w = binary 23 h = binary 8 x = binary 24 i = binary 9 (Hard tab) y = binary 25 j = binary 10 (Line feed) z = binary 26 k = binary 11 [ = binary 27 l = binary 12 \ = binary 28 m = binary 13 (Carriage ret) ] = binary 29 n = binary 14 ^ = binary 30 (CTRL SHIFTED 6) o = binary 15 _ = binary 31 (CTRL SHIFTED -) The above sequences rely on the standard operating system routines to decode the keyboard, however you can assign key values to any keyboard combination of your choice from the command mode. Of course you can also assign whole strings of text which may include binary control sequences to a key press combination. Most Amiga keymaps also support the ability to enter a variety of extended characters by pressing the ALT key, and another key, or keys. These combinations are not listed here. ***NOTE*** See the 2.0 compatability appendix entry below! ====================================================================== BLOCK & COLUMN MARKING ====================================================================== QED allows you to mark blocks, and columns of text. Mark mode is transparent; that is to say that you can continue to edit text, move the cursor keys, run macros, etc., while marking a block, or column. When marking a block of text: ----------------------------- The cursor position may not be in the marked block. This may seem confusing at first, but what it allows you to do is position the cursor on the beginning of a line, and move the cursor up, or down, only marking whole lines of text. It turns out that including the cursor position within the block in most cases requires MORE work on your part. Also you will find that QED's handling of marked block range works out very well when using the NEXT/PREVIOUS word feature to move the cursor. It is also possible to mark a range of text in which there are no real characters. For example, if free form editing is turned on, you could move the cursor past the end of a line, and mark a from left->right. However, if there are no characters in the area marked, attempts to cut, or copy this area will return an error message. Some experimentation is encouraged so that you will get a feel for how this mode works. When marking a column of text: ------------------------------ When marking a column of text, the cursor position is ALWAYS included within the column. However note that once again it is quite possible to mark a column of text in which there are no real characters. Some experimentation is encouraged so that you will get a feel for how this mode works. Note that some of QED's features are context sensitive. For example, SAVE AS can also be used to save a marked block, or marked column. The following features can be limited to a MARKED BLOCK ------------------------------------------------------- SAVE AS REPLACE ALL PRINT STRIP ERASE SWAP CASE FORMAT (SIMPLE FORMATTER ONLY) INDENT (MARK WHOLE LINE MODE ONLY) CUT COPY The following features can be limited to a MARKED COLUMN -------------------------------------------------------- SAVE AS REPLACE ALL PRINT ERASE SWAP CASE CUT COPY ====================================================================== DEFAULT KEY MAPPING ====================================================================== The following keys have been assigned default commands. Key Press | Action ---------------------------------------------------------------------- RETURN | Splits a line at the cursor position by inserting | a linefeed at the cursor position. If the cursor | is already past the end of line, then another | linefeed is inserted at the end of the current | line, effectively inserting an empty line. | Auto-Indent, and a variety of other options | can affect the behavior of this operation. | ENTER | Insert a new line below the cursor. | Auto-Indent, and a variety of other options | can affect the behavior of this operation. | SHIFT RETURN | Behaves like the ENTER key. | SHIFT ENTER | Behaves like the RETURN key. | BACKSPACE | Delete character to the left of the cursor. | If the cursor is on the first column, backspacing | can be used to join two lines, effectively | deleting the previous end of line character. | DELETE | Delete the character under the cursor, but not | end of line characters. | ESC | Opens the command mode window. | TAB | Inserts a soft/hard tab at the cursor position, or | moves the cursor to the next tab stop depending | upon the option settings. | CURSOR UP | Move the cursor up one line. | CURSOR DOWN | Move the cursor down one line. | CURSOR RIGHT | Move the cursor right one character. The cursor may | wrap to the beginning of the next line if free cursor | movement is off. Margin locking can also affect the | behavior of all cursor keys. | CURSOR LEFT | Move the cursor left one character. Cursor may | wrap up to the end of the previous line. Margin | locking can affect the behavior of all cursor keys. | SHIFT CURSOR | Move cursor up one window page. UP | | SHIFT CURSOR | Move cursor down one window page. DOWN | | SHIFT CURSOR | Move cursor to beginning of next word. RIGHT | | SHIFT CURSOR | Move cursor to end of previous word. LEFT | | ALT CURSOR | Move cursor to first line of window text. UP | | ALT CURSOR | Move cursor to last line of window text. DOWN | | ALT CURSOR | Move cursor to end of line. RIGHT | | ALT CURSOR | Move cursor to beginning of line. LEFT | | CTRL CURSOR | Move cursor to top of window. UP | | CTRL CURSOR | Move cursor to last line of window. DOWN | ---------------------------------------------------------------------- ***NOTE*** The ALT, and SHIFTED cursor key combinations do NOT conform to the new style guide standards. This has been done to maintain consistency with previous versions of QED; the default mapping of these keys may change in the future. ====================================================================== 2.0 COMPATABILITY ====================================================================== As of V2.0, QED requires V2.04 or greater of the Amiga OS. When running under version 2.0 of the operating system, QED uses your default screen font, which is the same font used by CLI windows to render text. ***SPECIAL NOTE*** You will not be able to enter control characters in the search, and replace requesters unless you turn "Text Gadget Filtering" off under the IControl Preferences editor.
