Unity super+d shortcut behaves differenly depending on speed of keypresses

[Ryan Prior]

Binary package hint: unity

Steps to reproduce:
* Launch any application
* Press Super+d in quick succession
Expected result: window flies to the background, revealing desktop. Dash is not triggered.
Actual result: window flies away, desktop revealed, but dash also triggered.

If super is pressed and held for a moment before d is pressed, the dash is not triggered. This is the expected behaviour.

Super+w also has this problem. You can press Super+w in rapid succession and get the expected window spread without any dash, but if you press Super+w again in a similarly rapid succession, the dash comes up as the window zoom back into place.

Notably, the expose/workspace switcher (Super+s) never triggers the dash, no matter how rapidly you press the keys.

Super + S is causing the workspace switcher which isn't gonna let anything new be created most likely, which is why that happens. This is an interesting bug.. it affects me as well, even though its never been an issue until i read this report and tried it.

This bug affects me as well. Though it's never been that much of an issue since i got to this bug and tried to reproduce it myself.
Yeah, Super + S is perfect, no Dash opens. Same behavior must be with other Super-Key shortcuts as well.

[John Pye (jdpipe)]

Me too! This behaviour is very frustrating... the feeling is that the system is doing something really quite unpredictable and random.

It seems that Unity claims the plain Super keypress for launching the annoying 'Dash' feature (what do I click to make that Dash go away???)

[John Pye (jdpipe)]

... perhaps the solution is to give the user an option in the "Launcher and Menus" control panel to turn off or change the Super (only, by itself) key behaviour?

[John Pye (jdpipe)]

... also, the Super-D keyboard shortcut does nothing at all once the Dash is visible. That keystroke should still operate as usual when the Dash is showing.

[Sparhawk (sparhawkthesecond)]

I'm seeing this too. FWIW, you can bind this to something else (e.g. Ctrl-Alt-D), and it won't trigger the dash as well. A bit annoying, as I'd like the Super key to do all the Unity-related actions, but at least this shortcut is usable.

AFAICT this bug seems to have disappeared in Ubuntu 12.04. Is that the same for anyone else?

[Omer Akram (om26er)]

thanks for the bug report. Is that still an issue in Ubuntu 12.04?

[Sparhawk (sparhawkthesecond)]

Both super-d and super-w work fine now for me in Ubuntu 12.04.

[Omer Akram (om26er)]

thanks for the quick response. Closing.
