Remove an Autocomplete Entry from Chrome

This tip comes from this stackexchange post

Linux and Windows

Just highlight it in the dropdown list (using the arrow keys, or your mouse cursor) and press delete on your keyboard.

Note that you may have to press shift+delete in some cases, like if the autocomplete is in the address bar (URL) field.

Mac

Start typing so that the unwanted autocomplete URL comes up.

Hit fn+shift+backspace if you have a compact keyboard or shift+delete ⌦ if you have a keyboard with separate delete ⌦ key (and no fn). If you have a non-Apple keyboard, shift+delete should do the trick.

If it still doesn’t work:

• Close the page and reload it; it should now be removed from autocomplete;
• Check if the unwanted URL is in your bookmarks; once removed from bookmarks, it will disappear from autocomplete.
