问题
I've been using Visual Studio 2005, 2008, 2010 on multiple PC's, installed there by other person or by me. Always intellisense suggestion on it worked like this:
I start typing, window pops with suggestions, with current suggestion highlighted, and I can press spacebar to accept the suggestion.
However, since i installed Visual Studio 2012 on my current PC (it is a relatively fresh Win7 64x install, it had VS2010 installed before) it works differently.
Now, it no longer highlights the suggestion. I have to use CTRL+ENTER to accept suggestion or DOWN to make it selected so that spacebar will accept it. This is really uncomfortable to use.
I tried resetting my settings (Tools -> Import and Export Settings -> Reset Settings) but it didnt help. It tried looking for help but noone knows or has this problem it seems.
What am I doing wrong? How to revert to old behavior?
回答1:
Do you have Toggle Completion Mode selected in Edit | IntelliSense menu? If so then click on it to unselect it.

I had the same problem. I know this worked for me when I was working with Java Script at least. Go to Tools>Options>Text Editor>JavaScript>IntelliSense Then make sure that the "Only use Tab or Enter to commit" is UN checked. Hope this helps, or at least gets you on the right track.
