Repeat "Press Keys" command up until marker

Hey!

I just started using SF and was wondering if there's a way to repeat the "Press Key" command up to a specific marker or end of a clip? The macro itself is really really simple but currently, I either have to stop it manually or let it run through 100 repetitions, which isn’t ideal.

Here's a copy of the script:

sf.keyboard.press({
    keys: "tab, p, comma, v, semicolon, tab",
    repetitions: 100,
    fast: true,
});

cheers,
Paul
