Modifier Keybinds will work too for this kinda thing, though it is much easier if you dont have to constantly use a modifier key.
And if it did not allow for Key Up and Key Down as events, then every Modder would have to implement a separate Auto-Do-Something version of their thing instead of just having to worry about using the Up and Down Events instead. I do not want to discourage people from implementing it right, which is why I wouldn’t leave it out.
And the auto-Repeat is already part of the Keybinds stuff if you looked at the Table.
