Set single key shortcut

I would like to set shortcut keys without modifiers. Is it possible with KeyboardShortcuts??

sindresorhus commented

I don't think that's possible. The low-level API we use expects both a key and modifier. Even if it were possible, it's not something I would want to support here. It's a niche use-case and it's easy to misuse it. You generally should not take over keys like that globally without a modifier.

For your use-case, it check out addGlobalMonitorForEvents(matching:handler:) (note that it requires accessibility permission).

If your use-case is to capture media keys, see: https://github.com/nhurden/MediaKeyTap

It is possible with RegisterEventHotKey, and it works in a playground.

In Apple docRegisterEventHotKey I see:

  • inHotKeyModifiers:
  •  The keyboard modifiers to look for. On Mac OS X 10.2 or

  •  earlier, this parameter must be non-zero, i.e. there must be a

  •  modifier specified. On Mac OS X 10.3 or later, you may pass

  •  zero.

However, when I try to modify your framework to accept 'no modifier', I get error -9868 when calling RegisterEventHotKey.
CarbonEventsCore.h says it's a "A generic error".

I understand you don't want this in your framework, but could you give me a clue?

Sorry, I have no idea.

Ok, one step further, I have put my plain RegisterEventHotKey sample code in a CLI and it works.
I put the same in an AppKit app (will check SwiftUI later) and it gives me error -9868.

Ok, I found the solution is pretty simple: The App cannot be sandboxed. Then all keys work.
