Single keystroke shortcut to undo autocorrect Is it possible to quickly revert an autocorrect with a single keystroke or combination?  As described in Shortcut to revert autocorrect change , the "correct" way to do it is:


backspace
wait
down-arrow  
enter
space


This is far too slow, and I often reflexively hit Command-Z instead, which has other unintended effects.

Are there other options, ideally without the use of backspace, arrows, or waiting?

Any advice welcome, Thank you!
Try this:

↑ up arrow after you type the word that autocorrects, but before hitting the spacebar.

This should dismiss the autocorrect without making the change in the first place.
