Move and Attack when possible
Attack + Move command. Units will stop moving when they can attack an enemy
Very handy if you don't want your units to run through dangerous areas full of enemies, but keep their distance.
Also works with Right Mouse Drag, to draw a line, just like the Move Line Drag command.
You can use Fight with construction and resurrect units as well.
Combat units = Move and stop to attack when enemies are within firing range
Construction units = Move and stop to Repair or Assist everything on the movement path
Resurrect units = Move and stop to Repair or Reclaim everything on the movement path
ALT + Fight
Resurrect units = Move and stop to Repair or Resurrect everything on the movement path
