Alt+E autocasts your shield on you so you don't gotta click yourself and drag your cursor away from your target.
Ctrl+any of your ability hotkeys (qwer) levels that one up for you so you don't gotta drag your cursor away from your target.
Gosh I hate myself for getting into this game enough to learn things...
