Cancel an autocorrect suggestion while typing When I am typing, OSX helpfully offers and inserts corrections for me.

However, sometimes I do not want these corrections, as they can ruin an otherwise flawless piece of writing (see the below example.)

Lifting my hands from the keyboard, gripping the mouse and then dragging the mouse across my frictious desk before contracting the muscles along my entire finger to squeeze the mouse and activate its clicking procedure actually takes a very long time.

How can I cancel autocorrect suggestions without needing to use my mouse?
Hitting ESC to get rid of the autocorrect suggestion works for me.
