A major change is made for my ergonomic based keybinding for emacs, on 2008-08-29. This page shows the change visually and gives a textual description on why.
Why The Change
Description of the main changes:
- Added delete-backward-char, delete-char, delete-backward-word, delete-word commands.
- The undo, cut, copy, paste, positions has been moved.
The reason for these changes is that recently Stefan Guath pointed out “real-last-command” can be used to fix the problem with “this-command” that is used in command-frequency.el. (“this-command” lumps several kill commands all into just kill-region, so frequency distribution for individual kill commands are lost)
With this fix, the stat shows that the commands to delete previous/next char/word are used some 10 times more than say, undo, kill line, or copy and cut. So, now these have prominent positions.
Here's a rough stat of the commands that changed positions due to the new finding:
cmd name frequency of use ------------------------------------- copy 174 cut less than copy paste (yank) 1691 undo 524 backward-kill-word 2303 kill-word 1074 kill-line 155 delete-backward-char 6558 delete-char 996
