The erognomic keybinding has a new version.

A visual image for old and new layout can be seen at:

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.

Since i don't use qwerty, i'm looking for feedback on qwerty users.
(i.e. in case i had some elisp code errors, or any issues that might
come up)


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 change, command frequent stat shows that the commands to
delete previous/next char/word very frequently used, 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 position 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
