What are the hotkeys for switching the current window between maximized, normal, and minimized states? If some of these don't exist, can I set them somewhere?

..for more shortcuts: What are Unity's keyboard and mouse shortcuts? – precise Jan 27 '14 at 7:18

In Ubuntu 12.04 Unity the shortcuts can be found in:

System Settings | Hardware | Keyboard | Shortcuts | Windows.

In a default installation the keys are the following:

  • Maximize: Ctrl+Super+
  • Restore: Ctrl+Super+
  • Minimize: Ctrl+Alt+0 (the keypad 0)

Minimize doesn't work for me either with the "0" key on the top of the keyboard. It does work with the "0" key from the keypad, however. – John S Gruber Aug 12 '12 at 18:48
It does work with the "0" key from the keypad, however. Even when the Numlock is off. Quite wierd.. – saji89 Nov 30 '12 at 5:52
I opened CCSM and found that Minimize is associated per default to <Control><Alt>KP0. not very useful on a laptop... luckily CCSM is meant for customizing this and more. – mariotomo Jun 27 '13 at 13:25
still worksish for 13.04. sub restore for minimize – user128334 Jul 25 '13 at 3:04
Still applies to 14.04. – igordcard Apr 29 '15 at 10:36

To minimize, it is not Ctrl+Super+0 but Ctrl+Alt+0.

It works on 12.04. Remember: Ctrl+Alt+0.

For me, control + super + D is minimizing showing the desktop. Again using it, restores the windows. – CR2 Mar 3 '14 at 8:31
Is there too a hotkey to restore the window? – tokam May 24 '15 at 18:40

For Ubuntu 11.10 and earlier:

Alt+ F10 : Maximize the current window. If the window is already maximized, unmaximize it(normal).

Alt+ F9 : Minimize the current window.

This seems to stop working anymore. – Christian Vielma Aug 7 '12 at 19:42
bagustrix's answer is the right one below. – galath May 28 '13 at 12:06
  • To minimise Alt+Space,N

  • To maximise Alt+Space,X

Depending on your internationalization settings the key to press after Alt+Space will be different (e.g. U to minimize with french settings).

This will minimize only current window. Is there anything to minimize all at once/ – CR2 Mar 3 '14 at 9:08

If the defaults don't suit you, you can set new shortcuts by opening the Dash and searching for the app "Keyboard Shortcuts."

For Ubuntu 12 Unity:

Maximize: Ctrl+Super+

Restore: Ctrl+Super+

Minimize: Ctrl+Alt+0

Bottom-Left Corner: Ctrl+Alt+1

Bottom: Ctrl+Alt+2

Bottom-Right Corner: Ctrl+Alt+3

Maximize or Center: Ctrl+Alt+5

Top-Left Corner: Ctrl+Alt+7

Top: Ctrl+Alt+8

Top-Right Corner: Ctrl+Alt+9

Fixed the minimize shortcut by changing the shortcut to Alt+M and now it works perfectly fine for me.

How did you change the shortcut? Could you add that to your answer please? – John S Gruber Aug 12 '12 at 18:48

Strangely enough, in my Ubuntu 14.04 using KDE it's Alt + Middle Mouse Button.

Found in: Start->Computer->System settings->Window actions->Window behaviour

On Ubuntu you can find your shortcuts in System Settings -> Keyboard -> Shortcuts. As well, you can show some shortcuts by holding the Super (Start) key.

In Ubuntu 15.10, it works with ctrl + alt + 0 (on the numberpad).

However, I prefer to use ctrl + super + arrow down key.
