I meant that the code for working with the secondary selection has
been set up in a quite meticulous way so I would never mess with it
(including the modifiers it uses).

I usually shift-control with my pinkie alone so I would consider it
optimal and use it for many key combinations all the time.

These deserve their bindings though I would not pop up a menu from a
mouse-down event alone.  What I am obviously assuming is that the
rectangular region selection code is based on mouse-dragging from one
corner of the rectangle to the opposite one, so a mouse-drag is easily
distinguishable from a click for a pop-up-menu.  If this assumption is
wrong, my rebinding proposal is clearly void.
