Configure pen and touch events, e.g. to disable switching pages/overlays

[torwag]

One of the most frequent mistakes I do is that I try to write something on the slide but having not selected the pen mode.
As a result, both my hand wrist or the pen, would be recognized as a switch to next slide/overlay.
That is annoying for the presenter and quite confusing for the audience.

It would be nice if one could configure pdfpc to not switch slides overlays on touch or pen contact. Furthermore, approaching the display with the pen (at least for me) it is almost always clear that I want to write something. In that case, I would prefer if the pen is selected automatically. For the laser pointer on the other side, I use my finger and the touch screen functionality. However, I can see that this might be different for other users.

To summary: It would be nice if users can customize what should happen on pen and touch events, as this might greatly enhance the different workflows.

If this feature request or a derivative gets approved, I would be willing to look into it.

It's quite easy to implement. But the problem is how to switch back to the normal mode automatically.

Not sure how you do it. Is your touchscreen responding to your finger without actually touching it (like an active stylus)? Otherwise, moving a finger will be interpreted as a drag (highlighting a rectangular area in pdfpc).

However, I can see that this might be different for other users.

Right, the issue is how to make the behavior flexible enough.

@torwag ping?

Sorry, I confused myself.
I use the mouse (touchpad) to move the laser pointer and use the pen to write.

I can see how this might be a bit difficult to set up.
Maybe a mode where using the pen is drawing exclusively, whereas using the mouse is the laser pointer exclusively,
Because at least for me, I constantly mix up and draw lines, where I was thinking of showing something, highlight something, or zoom in,
Vice versa, I constantly start to write with the laser pointer, with the pen instead of switching to the pen function.

Sorry, for the early confusion, my main machine is a non-pen machine and my presentation laptop is the one which troubles me. Writing here happens on my main machine, giving lectures on my presentation machine. I somehow mixed up stuff.
