Ctrl-] in vi or vim means "go to tag", it goes to the definition of the symbol under the cursor. In ViEmu, it invokes "Edit.GotoDefinition", which is the equivalent function.

By default, in Visual Studio, it invokes Edit.GotoBrace, which I think is equivalent to the vi '%' motion.

Good, you're welcome

Some extra comments on %: if you use it at a non-matching character (ie, not one of "()[]{]"), it will scan to the right in the current line to find a matching character, and find the match of that one. The advantage is that, if you have a function call:

  a = fn(b, c);

and you have the cursor on the 'f' of fn, "d%" will delete the whole function call. Very useful.

vi/vim also matches #ifdef/#endif, etc., but ViEmu doesn't do those yet.
