I have set up Lion text replacement to replace a three-letter short-code with my full email address. It works great, and I recommend you all do it. :-)
But - in order to confirm the auto-replacement, I need to press the space key (similar in iOS). Often for web-forms, etc. I don't want that space to be there.
Does anyone know if there is a keystroke which will select the suggested text auto-replacement without adding a space?
