Clear Autocomplete Cache?

I made a typo when using ‘FullSimplify’ (wrote ‘FullSimpify’ instead) in Mathematica, and now whenever I use the command autocomplete feature the default selection is my typo. Is there a way to clear the saved autocomplete functions so I can press tab to get the correct autocomplete function again?

Either quit the kernel and start a new session or evaluate the following:

Remove[FullSimpify]
