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.
