@burnout426 This wouldn't solve the issue as the moment they type the "y" in "yt" it would move to the yahoo search and then type a "t" afterwards. This is the issue with how things work currently and is why I opened this thread so long ago and have since moved away from this browser.
Edit- In hindsight I just remembered the problem only triggers after you put in a space from the shortcut letters. So this would probably work for their issue, my bad.
