Moving by symbols
The ctrl-] key (in normal mode), jumps to the symbol under the caret.
If no tag was found, Vico tries to match the current word with a symbol. If more than one match is found, you are presented with a menu.
If a tag or symbol is found, the current location is pushed on the tag stack, and the caret is jumped to the new location. Press ctrl-t to go back.
You can also use the ⇧⌘T key to search the symbol list.
