Windows – How to disable Alt+Space native hotkey in Windows 10

hotkeyskeyboard shortcutswindowswindows 10

Windows 10 has Alt+Space as a default hotkey for opening the menu bar of a windows with the choices of Minimizing/Maximizing it.

I'm using Kdenlive and Kdenlive wants to use Alt+Space as a hotkey for playing a video in a loop. Unfortuntely, when I press the hotkey Windows 10 processes the hotkey without the information getting passed to the app.

Given that I don't need the native hotkey, is there a way I can remove it?

  • Alt+Space hotkey is taken by Windows system by default.

    However with the help of a 3rd party solution you can override this setting and take control over Windows by not letting them to steal the hotkey combination.

    1. Download Autohotkey and install it.
    2. Create a new file in Notepad or your default editor and insert these 2 lines:

      ; it allows to make a rule which is applied only when windows contains the given title
      SetTitleMatchMode, 2 
      ; obviously below you write the title that is contained in your program's window 
      #IfWinActive, Kdenlive
      !Space::Return ; ! stands for Alt key
    3. Save it somewhere easy to access it as Whatever.ahk (and not as .txt)

    4. Double click on it (or Run as Administrator) and it will trigger AutoHotKey to execute it and have it loaded. Now the Alt+Space hotkey does not call the Windows default actionwhen is hit in a window with the given title (Kdenlive).

    I suggest to put it on your startup programs for not having to execute it manually each time you reboot your system.
