There have been several implementations copying the basic mouse
commands from Genera in GNU Emacs:

I stopped pursuing the idea after discovering that mouse use was
giving me wrist pain.

I'm currently working on a project where I am bringing Maxima to CLIM (I've had some pretty good progress), but one thing that has frustrated me is that CLIM does not have a consistent concept of keyboard control.

I believe this comes from Genera. I wonder if it was designed at a time where it was thought that mouse control would be the primary mechanism of interaction.
