Any reason you can’t use a pedal? What instrument do you play?

Sorry, if it's already known or posted.
I use for some purposes a Flic Button https://flic.io
Works pretty well on iPad or Android (Boox Tab X).

I bought a cheap ring turner. It has 3 buttons and is paired as ZL03 keyboard. I can set up long presses but that's not ideal. I did find that with Performance Mode active, the middle button works with one click to change pages, which is what I wanted. Unfortunately, the other buttons do long swipes which, although fine on a 2 page piece (the majority of multi page music I have), on a longer piece (or hymn book, for example) it changes multiple pages, which is useless (it's sensing a fast swipe up).

So it works adequately in Performance Mode but otherwise brings up the annotation menu (which I like having active with Stylus sensed so can't uncheck that).
