Keys

Ted's editing keys are a modified superset of the standard Text widget bindings. That is, editing actions such as movement typically use the control key. The first section contains a quick reference of the main control keys. The subsequent sections group the keys by function.

Shifted Keys and Selection

All move commands have shift'ed versions to select data while moving. ie. holding down the shift key and using a move key will extend the selection. Note while the anchor is maintained for keyboard movements, a mouse will click reset it.

Control-; serves a dual purpose. If not text is currently not selected, it reselects the previous selection (ie. anchor to insert). Otherwise, it pastes the selection to the last insert position. This is roughly equivalent to: Control-c Control-' Control-v, or using Control-B1 after a selection.

Named Buffers and Position Marks

Marks are simply positions within a file named from 'a'-'z'. Tags are similar to mark, except they also have end positions, ie. tags delimit blocks. Lastly, there are buffers which are used for managing cut, copied and pasted data. In the following commands, the cursor changes to gumby when a buffer name is required from user. If there is no selection when "Yank" (Control-y) is used, you will be prompted for a mark name position to yank from.

A buffer name "/" can be used with "Yank" to write to a file or with "Load" (Control-l) to read a file.

To display all buffers, use Control-l then release and repress Control.

Text Binding Differences

Copy, Cut and Paste all work differently than the standard Text widget. In the standard Text widget when there is no selection, Cut and Copy do nothing. The new behavior is that if nothing is selected, the current line gets Cut or Copied.

When there is a selection, Copy gives visual feedback by automatically deselecting text. Paste will delete any previously selected text before doing insertion. That means paste is now actually replacement. Also the inserted text is left selected until the Control key is released to allow further Control operations to occur. (If the original paste behavior is required, you may use <Control-Alt-v>.)

The following sample session is the command-line equivalent of the search and replace dialog.

  <Control-s>      # open find dialog
  FOO              # enter some text and hit enter.
  <Control-Insert> # change to auto-selected input mode
  BAR              # enter replacement text, auto-highlighted
  <Control>        # press and hold Control key
  c                # copy to buffer, which also exits select-input mode
  /                # repeat last find
  v                # paste buffer
  /                # repeat last find
  v                # paste buffer
  ...              # release control key when done.

Mouse Functions

Basic mouse functionality works as follows:

  - Clicking mouse button 1 <B1> sets the insertion point.  
  - <Shift-B1> sets the insertion point and extends the end of the selection.  
  - <Control-B1> changes the insertion point without affecting the current selection.
  - <Double-B1> highlights the current word.
  - <Control-Double-B1> toggles a breakpoint.
