You are both right, and I, too, would prefer a better modifier than 
control-meta.
Platform conventions vary, although right-button is clearly dominant for 
context menus today. There is no similarly agreed way to select rectangles of 
text.

Nevertheless, I would like this patch to be pushed as long as there is no 
objection to the design and implementation of the feature itself. It uses 
nobody's favourite binding, but at least the feature is accessible in a useful 
way. With it in place, we can argue about shuffling bindings around.
