Public bug reported:
When I'm using Bash in gnome-terminal, I'm currently unable to use the
GNU Readline shortcuts to move forward a word, because pressing Left Alt
+ a key tries to open a menu option. For example, Alt+f opens the file
menu. For some reason, the Alt key is bound to the menubar here.
Expected behavior: Alt+f moves the cursor forward one word
Current behavior: Alt+f opens the file menu.
The strange thing is that it does work in a GUI version of Emacs, but
not when Emacs is run directly in the terminal (emacs23-nox). It also
works correctly in xterm (after Ctrl + left-click > select "Meta Sends
Escape"). So I'm not sure if it's a bug in gnome-terminal or in unity.
When you hold the Alt key in Emacs or xterm, nothing happens, the HUD is
only displayed when you release the key again. Of course, when you're
using it as a meta key, you're never doing that, you're holding it and
combining it with another key. So that's the correct behaviour. In
gnome-terminal, however, holding the Alt key doesn't do anything. It
seems to be the case that combinations using the Alt key are interpreted
as shortcuts for the menubar in gnome-terminal.
On a related note, I'm wondering whether binding Alt to the HUD won't
conflict with the usage of Alt as a meta key? While Alt is the obvious
choice (and I like the concept of the HUD), it would be very annoying to
be unable to use the meta key in certain programs.
