Re: [PyMOL] Middle mouse button in Mac Pymol does not work?

Hi Jason,

Middle mouse button always worked fine for me with MacPyMOL, using any kind of "normal" mouse (two buttons + wheel as middle button). I haven't tried a magic mouse, but also never received bug reports that those wouldn't work with MacPyMOL.

Could it be that any third party tool interferes here (like BetterTouchTool)?

A PyMOL script or plugin could also possibly redefine mouse actions (like https://pymolwiki.org/index.php/Mouse_modes ). You can suppress loading of plugins and pymolrc scripts with the -k flag (launch from Terminal as /Applications/MacPyMOL.app/Contents/MacOS/MacPyMOL -k).

It's true that a trackpad doesn't fully replace a 3 button mouse. ALT+click mimics the middle click, but it looks like SHIFT+ALT+drag doesn't work.

The mouse action codes are not documented anywhere. But you could have a look at the cButMode names, which are a bit more meaningful:

Cheers,

I usually cannot get the middle "M" commands to work, either with an old button mouse, a Magic mouse, or a laptop trackpad. I have tried Better TouchTool without success. In 3-button editing mode, the middle button is supposed to Move or MovO, but it just rotates instead. This makes any sort of docking much more difficult.
