"E" and "W" do not seem to be working correctly for unit selection. I left-clicked a unit, then held down the "E" or "W" and lef-clicked another unit in the same squad.

It's "e" and "w", lower-case. Anyway, as Grame said, just select a unit, then tap "w" or "e" and other units in the group will become highlighted.
