IMHO, if one is expecting to use vim (as opposed to gvim), mapping <Esc>
causes trouble.
That's because most terminals issue escape sequences
(<esc>..something..) when special
keys (such as the arrow keys, functions keys, etc), and that mapping of
the <esc> key
messes up the escape sequence. Besides -- how do you get out of insert
mode? I realize
one can use ctrl-o and norm!, but that seems painful. If you're not
using normal mode
or command mode, then you're missing a lot of vim.
