Macro for App Switcher while holding ALT-TAB ?

[matt22207]

Hi, I have a macro keypad setup for shortcut keys, and I can't figure out how to get a proper ALT-TAB combo for app switching. My basic attempt is KEY_LEFTALT + KEY_TAB which works properly on a single press of the key to switch between apps. However when using my normal keyboard, I can continue holding the ALT key (after releasing TAB) and then subsequent presses of TAB or arrow keys will cycle through the open apps. I've tried a few combinations using hold_keys(), etc, but I don't understand and can't figure this out myself.

So, I'm trying to reproduce:

• A single press of the macro key should trigger a single press of ALT-TAB
• Holding the same macro key should press ALT-TAB once, then release TAB and continue holding ALT (only) until the macro key is released

Would someone mind helping me figure out the proper macro to use for this?

Thanks!
