Back and Play (keep selection) on regular Pro Tools (not Ultimate)

Hello !
I Had the same issue today, here what i came with :

const isPlaying = sf.ui.proTools.isPlaying;

if (!isPlaying) {
    sf.keyboard.press({
    keys: "numpad multiply, numpad minus, numpad 0, numpad 2, numpad 0, numpad 0, numpad enter, space", 
    repetitions: 1,
    fast: true,
});
}
else {
    sf.keyboard.press({
    keys: "numpad multiply, numpad minus, numpad 0, numpad 2, numpad 0, numpad 0, numpad enter", 
    repetitions: 1,
    fast: true,
});
}

It detects if PT is playing, then use the sortcuts to go 2s
In this case, it works only if Pro Tools main timecode is in HH:MM:SS:FF but i think you can change the keys to press to suit your workflow better.

Unfortunately, this script does not keep the selection.

I have a Avid Dock so i mapped the Back & Play button to a key combination witch wasn't already used by Pro Tools :

Then I set up a trigger in Soundflow like this :

Hope it help you !
