Global hotkey KeyDown and KeyUp Events

Question

I'm trying to implement a global hotkey logic in my program when I press down and up a key. The hotkey needs to be global. The behaviour is simple: When the F10 key is Down, the form is visible, when released, the form hides itself.

I managed to implement the WMHotkey procedure, but I need it to be split into Key Up and Down. Is there a way to do this with global hotkeys?

If you're trying to directly capture the messages, you're gonna have a lot of complications. Why not use Delphi's actions with their hot key support? — Jerry Dodge, Feb 14 '20 at 00:47
There will be complications with WM_HOTKEY, see https://stackoverflow.com/questions/20149761/delphi-xe3-wm-hotkey-how-to-tell-when-hotkey-is-released , go for one of the alternatives. — Sertac Akyuz, Feb 14 '20 at 02:13
@Jerry - Global is when the application is not in the foreground I guess. — Sertac Akyuz, Feb 14 '20 at 02:14

I managed to accomplish what I was trying to do by implementing the code that RRUZ provided in this question: How to monitor the keyboard above all other applications and then send other keys to them instead.
