Accidental move command

I don't know if you guys have ever made this mistake... but forgetting to A-move when you're trying to move your main army around the map, is just heart-breaking. It's a habit I've almost shaken now, but it used to be the most frustrating thing in the world, as I would see my army has been engaged, quickly double tap the control group to see what's going on and realise I have already lost like 3 colossi in 5 seconds because they were not fighting back :(
