Bug Description

I frequently use the Super + [0-9] keyboard shortcuts to switch to specific applications. However, these shortcuts usually fail to work when executed quickly. In order to ensure a successful application switch, I have to hold down the super key for at least half a second (long enough for the launchers to appear on the left) before pressing a number key. If I press the number key too soon after starting to hold down the super key, Unity simply acts like I had not pressed the number key at all. It either shows the Dash if I let go of the super key fast enough or if I keep holding it down, it shows the shortcut overlay (i.e. whatever would have happened anyway if I never pressed the number key at all).

This was not a problem in 11.10 and is became a problem in 12.04. It really breaks my flow when it happens and I end up holding down super and mashing the number keys repeatedly until the right applications finally comes up.

Note that it does not always open the dash, it's merely one of many side effects. More often than not it will just not register the change and write "2" or "3" into whatever program I'm using at the time (A severe annoyance when using vim, let me tell you!)

As far as the issue goes, I can confirm it to be the case on Asus 1215P netbook that I have for testing.

apport information

Here is a video demonstration of switching between terminal and nautilus (super 2 and super 3, repectively). Note that it does not always open the dash, it's merely one of many side effects. More often than not it will just not register the change and write "2" or "3" into whatever program I'm using at the time (A severe annoyance when using vim, let me tell you!)

summary: - Unity Super+[1-9] shortcuts to switch apps don't work consistently
+ Unity Super+[1-9] shortcuts to switch apps don't work consistently when
+ pressed quickly.

Also, I will add that this did not affect me on 11.10 at all - things could be quickly pressed. This all started upon upgrade to 12.04.
