When I'm in combat, what slows me down the most is when a combine attempt fails. If I see two glyphs to combine, say 1 & 2, I rush to hit 'R','2','1'.. The problem arises when Glyph 1 slips away just as I hit '1'. The combine fails, and I'm stuck with a red box around a glyph that can't combine to anything. Meanwhile, I can't click on ANY glyphs to activate them until I hit 'R' again. That extra keystroke that only occurs when a planned combine fails interrupts the flow of combat every time. I would much rather be sent out of 'combine mode' after that second key stroke, no matter whether it was successful or not. I should be able to hit 'R','1','#' and be back out of 'combine mode' and continuing the fight, no matter what that number was - it could even be 'R','1','1' (an obvious fail) - the point is it should matter whether the combine was successful or not. This one change would make combining glyphs so much less painful.
