Re: keyboard-translate working for Control but not for Alt

[Xah Lee]

additional info i just found out ....

this method
(global-set-key (kbd "C-t") ctl-x-map)

turns out to have other problems as well, when cua-mode is on.

with cua-mode on, and when you have a text selection, you need to
press C-x twice quickly to invoke the traditional C-x role. (at least
as one of the method, anyway) So, that means you press C-t twice
quickly.

One example i'll need to do this many times per day is “C-t r
t” (string-rectangle) and “C-t r k” for kill-rectangle, where you do
need a selection on first.

With
 (keyboard-translate ?\C-t ?\C-x)
i used in the past, i didn't encounter problem.

i started to use cua-mode since last year, not because i need it, but
more for testing compatibilty with my ergoemacs setup.

So, with cua-mode on, and with
(global-set-key (kbd "C-t") ctl-x-map),
now “C-t r t” no longer works... it seems to be calling transpose-
lines...

in short, all these extra personalized fixes creates a lot
complications. If emacs dev made cua mode's intended purpose by
default, which as a side effect most of these complications will be
gone, as compared to indivdualistic customization that tried to
achieves the same thing. This is because when emacs has something out
of the box, the implementation is more throughly examed at some lower
level, i.e. creating much more robustness than individual hacks. If
emacs dev decided that Ctrl + XCV should be the shortcut for emacs,
the proper solution is probably not even using cua-mode, since itself
is a quite complex hack.
