Mac: highlight the entry and then press Fn + Shift + Del
PC: highlight the entry and press Shift + Delete
- Update, 7/29/14 - From my own personal trial and error, this is only working for me on items specifically in my history, either URL's or previous Omnibox google searches, but not google's auto suggestions. To delete an item from the omnibox on mac, arrow over it and hit
Fn + Shift + Del
or justShift + Del
for some people it seems (not me).
