I am using MaMuT for the annotation. Previously, I was doing that on Ubuntu machine and everything was fine but after switching to macOS I've noticed problems with the keyboard shortcuts.
"Arrow up" increases the time step instead of zooming in.
Letter shortcuts, e.g. "M" and "N" are not working at all.
I've tried to change the active window switching between main and annotation windows but it didn't help.
The problem doesn't show up instantly after starting MaMuT but only after some time of using it.
@tinevez, is this a known issue? Ideas why this might happen?
