I'm thinking about making "enter" deselect an object box and connect it to a new, empty one. This would make editing a lot faster.
if that's going forward, maybe enabling tab and sh-tab to move around
boxes as well. that would be one step further.
by the way, is it possible to make the properties boxes of atoms, canvases
and etc. (basically all standard objets which aren't from iem) also more
keyboard-friendly? like being able with tab / sh-tab to jump between
parameters?
