# 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.

Thank you in advance!

• The auto-completion doesn't know anything about the source properties (i.e., it doesn't distinguish characters) and therefore must use spaces as a way to delimit the completion strings. I don't think there's any way around this short of making a feature request to the TeXShop team. If you make your completions begin with \ then you can avoid the space. – Alan Munn Oct 6 '18 at 21:05
• Thank you very much for your comment @AlanMunn! It's very nice of you. – Collin Oct 7 '18 at 16:34
• Since I think that's the only answer, I'll convert it into an answer. – Alan Munn Oct 7 '18 at 16:52

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