That's correct, but I've never gotten false input before. If my setup gave me false input even 0.5% of the time, I wouldn't use it at all. I give myself 250 mil

That's correct, but I've never gotten false input before. If my setup gave me false input even 0.5% of the time, I wouldn't use it at all. I give myself 250 milliseconds to release the ; key to type it as normal, and that has worked fine for me, both on my laptop keyboard and on my external keyboard. I find it very easy to use since my pinky finger sits on the ; key by default.
