Key loops

[cmb991]

Hey all, I’m sure this is asked all the time, but everything I’m searching has different methods and I’m lost.... I’m trying to setup a script to send the key ; every 5 min, and ‘ every 15 min. I got started with the script below but I’m lost. I set the sleep to 10 just for testing.
I’m also trying to put a script together that will hold the ` button every 10 minutes for 5 seconds.

Numpad0::
Send {;}
sleep 10
Send {‘}
return
