Hello,

I am just starting to use Coot 1.1.20

We are at 1.3.1 now.

 on macOS Tahoe with an external monitor and am hitting the mouse alignment/centering bug(?) when moving between the Retina screen and the extended display.

If you mean OpenGL widget scaling, then I know what you mean.

The manual fix via /Draw -> View -> Scale Down Graphics/ works well, but I have to do it constantly.

Is it possible to bind "Scale Down" and "Scale Up" to keyboard shortcuts in Coot 1? I tried the 0.9.1's add_key_binding, but it is not working.

See attached. Bound to keys 5 and 6.


Paul.
