Global Hotkeys

I need a code that toggles something even though the form is not focused.

You need to have a listener for the event, which in this case are the hotkeys. Your app should register the keys as they are clicked if you have a listener in the background.

You can do this too.
if you have NuGet.
Install MouseKeyHook.
Follow the documentation.

From my halted project:

Code:

class Extern { [DllImport("user32.dll")] static extern short GetKeyState(int key); private const int KEY_PRESSED = 0x8000; public bool IsPressed(int key) { return (GetKeyState(key) & KEY_PRESSED) != 0; } }

Hope you'll be able to put it to good use
