https://shop.turntouch.com/pages/how-it-works says, “Don’t know what a button does? Press all four buttons to show a heads-up display (HUD).”
Show it where?
The HUD is only on the Mac. It allows you to run actions from apps that are not connected to another of the buttons. Super handy, but alas Mac-only as it is interactive and wouldn’t make sense on an iPhone.
That said, I’m considering an alternate action for multi-touch, on both iOS and Mac. Happy to hear ideas.
Related question, can I disable the HUD? I’ve accidentally opened it during presention practice more than once and ended up switching button profiles without realizing it.
Would you prefer if I just automatically disabled the HUD while in the presentation?
Ok, I just released v1.0.1 of the Mac app which includes a new setting to disable the HUD entirely.
