This page allows you to customize aspects specific to Text Compare and Text Merge sessions.
Editing features
Auto indent
When enabled and a new line is created, it is automatically indented to match the leading whitespace on the previous line.
Backspace unindents
When enabled and positioned immediately after the leading whitespace on a line, pressing the BACKSPACE key deletes enough whitespace to match the previous indentation level, as defined by preceding lines.
Allow positioning beyond end of line
When enabled, the edit cursor is not constrained by the end of text on a line.
Display options
Most of the display settings for Text Compare and Text Merge are found on the Display and Compare Colors pages of the Options dialog. Settings specific to the text editors are here.
You can add or subtract pixels from Extra line spacing to change the density of text in the view.
To show a vertical line at a specific column position, set Show column line at to the desired value. Set it to zero (0) to hide the line. If you use a proportionally spaced font, the column position will be determined by the width of the space character.
Enable Show filtered line counts to display a summary of lines hidden by display filters:
To use an alternate font for the narrower input panes in a Text Merge session, enable Different font for merge input panes.
Other miscellaneous options
Initialize "Text to find" to be current word
Causes the current selection to be filled in as the search text for the Find 
command.
Number of context lines
Defines the number of matching lines to display before and after a difference section when the Text Compare's Show Context 
is used.
