When I'm adding an equation driven sketch dimension and I start the equation with an '=' sign, a dropdown list immediately appears listing all the globals. Very useful. But if I start the equation with a number, the globals list doesn't pop up again under any circumstance (unless I type another incorrect / inapppropriate  '=' sign, which SW doesn't allow).  Anyone know a workaround for this?  I have to manually type the global with quotes. Very inefficient.
