This is an excerpt from Starcraft Shift queue command guide. Something similar in the pipeline for Outscape? Would help immensely with not only scouting but also general move/mine/attack/whatever commands.
Using the Shift Key: The Basics
The following uses for Shift are more than just ‘cool’ or ‘tricky’, these are the crucial things that you should use every game if you want to play well.
Hands Free Scouting
You can queue up multiple move commands with any unit by holding the Shift key and right clicking for each point you want the unit to move to. Using this your unit can scout for your enemy’s base, proxy buildings and expansions without your direct control, freeing you up for more important things. You can even do this via the mini-map!
This is merely a variation on the previous Shift technique. Instead of queueing up multiple
Move-commands you can queue up multiple Attack-move commands. Simply press ‘A’ (or your equivalent attack hotkey) and left click each point you want your unit to attack move whilst holding Shift. You can use this technique to find and attack any stray workers or Overlords around the map. Having a few units Attack move scouting around the map can really help you maintain map control and deny your opponent’s scouting attempts.
