# How to leave out the Space before I use auto-completion by Tab in TexShop?

These days I am trying to improve my typing speed on TexShop by employing the Command Completion source. However, I've found that I have to type in a Space before using, say, "xg+Tab" to represent \gamma, even when the character right before it is not a letter but something like "+","/" or other special characters (so in such cases I think that the editor should not be stupid enough to misunderstand what I'm trying to do).

Thus I want to know how to activate auto-completion without typing in a Space all the time.

So if instead of using xg as your auto-complete string for \gamma you use \xg, things will work well without needing the space.
