When one is inserting parentheses some folks like to see the cursor
bounce off the matching parenthesis.  To do that, put the following
map into your <.vimrc> file:

    inoremap ) )<c-o>%<c-o>:sleep 500m<CR><c-o>%<c-o>a

Adjust the time delay (its 500 milliseconds above) to suit your needs.

Somewhat better map:

  inoremap ) )<left><c-o>%<c-o>:sleep 500m<CR><c-o>%<c-o>a

There was a problem when inserting parentheses into previously
existing text which the <left> handles.

Vim 6 has this functionality built-in.  See the 'showmatch' and 'matchtime' options.

I think the difference between the built-in functionality and this mapping is that this mapping works even if the matching bracket isn't currently visible on-screen.  The documentation stipulates that the 'showmatch' option only highlights the match if it's actually on-screen.

Matching a paren not on-screen can be scroll your screen unwantedly...

If you'd like to have the corresponding parenthesis, brace, or curly brace
highlighted, check out vimtip#177.

This fails if you have a vertical window to the left of where you're editing.

what about when the matching parenthesis is no longer in the window? (for example suppose your window begins and ends at '-----''
int main()

when you type your '}' how do you get that to match when it is no longer in the window?
