Minimize window default shortcut Ctrl-Alt-0 doesn't work

[Jussi H.]

Using shortcut Ctrl-Alt-0 doesn't work to minimize window. It's show in System Settings->Keyboard shows as default.
After testing to find what key combination actually minimized window it was Ctrl-Alt-KP0 (keypad 0) that minimized window.
When changed minimize window shortcut by hand to Ctrl-Alt-0 it started working and after that Ctrl-Alt-KP0 didn't work anymore.

Ubuntu 12.10
Unity 6.10.0
gnome-control-center 1:3.4.2-0ubuntu19

I can also confirm this. However, I am not sure if it is not the intended behavior, in which case maybe a better way to indicate the shortcut in the control center should be found.

Seems that if i change shortcut to same Ctrl-Alt-0 it works but after reboot it's not working anymore and I have to do it again.

The design is for Ctrl+Alt+number pad 0 to minimize windows.

The reboot problem has been reported in bug 1064872.

Did you read my comments? If i change minimize to Ctrl+Alt+0 it's reseted to Ctrl+Alt+KP0. Also keyboard shortcuts settings show minimize shortcut as Ctrl+Alt+0 even if it's Ctral+Alt+KP0.
So i'm really wondering how this bug can be invalid?

[Jussi H. (jussi-h)]

What I mean is that Ctrl-Alt-KP0 showing as Ctrl-Alt-0 in keyboard shortcut is still a bug even if that shortcut reboot thingy is reported in another bug.

I ran into this just now myself. It's pretty confusing. If I didn't find the AskUbuntu entry http://askubuntu.com/questions/56170/unity-hotkey-for-minimizing-current-window I wouldn't have known to disguish key 0 from KP0. Now that I know, it makes sense. But I think the 'Keyboard' control panel should report 'Minimize Window' as Ctrl-Alt-KP0, not Ctrl-Alt-0. If X Input disguises them as different keys, then it should tell the user that's inportant.

So I don't think this one's Invalid. It may perform as you expect, but that's only once you have the right expectations.

I agree with Jussi and Mike from comment #4, #5 and #6. You need to think of this from a new users perspective who is new to Ubuntu and perhaps not as technical. I was a little confused why Ctrl-Alt-0 was not minimizing the windows, then realized they correct keystroke is CTRL-ALT-KP0.

This is completely misleading, we should at least fix the dialogue so it clearly states (Ctrl - Alt - Keypad 0).

when seeing Ctrl - Alt - 0 one will assume that both 0 on the keypad and 0 on the numberbar will minimize the window.

Reopening. Sorry about that!

It's almost two years to the day of the original post and in Ubuntu Gnome 14.10, this has not been fixed.
