Title:
Regression: Alt invocation of search cannot be remapped, causing pain
to Emacs users
Status in Unity:
Incomplete
Status in unity package in Ubuntu:
Incomplete
Bug description:
A long while ago, we Emacs users requested that it be possible to
remap HUD search invocation away from Alt (and especially left-Alt)
since this is a very common key chord prefix for Emacs. At some point
this was done.
In my recent bug LP: #1278582 I mentioned that the binding disappeared
in the System Settings->Keyboard->Shortcuts window, but that bug has
both been resolved, and a workaround was described by seb128 and tedg
in irc that I could use gnome-control-center.real. That does indeed
show me the "Key to show the HUD" setting.
However, we still have a pain-inducing regression here ;). That
setting is "Disabled" on my system, and yet the Unity/HUD search
dialog is still invoked when hitting either left-Alt or right-Alt.
Something consumes the first press of the Alt key so that it does not
get passed to any window. I've confirmed this with Emacs, Claws-Mail,
and Terminal. For example, if I hit Alt-F with focus in Emacs, Emacs
does not see this key binding. If however, I only release the 'F'
key, holding down Left-Alt, and then tap 'F' again, Emacs will see the
key the second time. Claws exhibits very similar behavior (e.g. I
have expunge bound to Alt-K - Claws only sees the second tap of
Alt-K).
Even worse, if in the course of trying to tap e.g. Alt-F in Emacs I
happen to quickly tap Alt (either left or right), then the search
dialog comes up and all subsequent typing is diverted to search
instead of to Emacs. This is highly disruptive as you might imagine
;)
At one point, I had hud and the launcher invocation remapped to Super
(and right-Super in fact) and this is much more conducive to Emacs
users. On my Trusty box where I've delayed updating to the latest
archive packages, hud/unity search is still invoked by Super and *not*
by Alt. However, on my fully updated Trusty machine, I experience
this regression.
