Ahk press and hold temporarily

[CrazyManPlayz]

Hello, sorry I am really bad with scripting on ahk lol, imma explain what I basically want this script to do and maybe someone could help?

So if i press F5, g will hold down for half a second then release on toggled loop until F5 is pressed again.

And if I press F6, g will hold down for 5 seconds and then release and press w and double jump approx 4-5 times.
If you could help me with this, that'd be highly appreciated!
