Dear vim_dev,
Recently I tried to make a user function for jumping through the jump
list (by files), but it happens that there is no good interface for
that. For example CTRL-I could possibly be only with :normal! <c-i> but
this does not work (even in vim -U NONE in the terminal, I have not
tested this in the GUI though) and also using CTRL-V will not work since
CTRL-V_CTRL-I produces a tab (this works with CTRL-O thought).
I present here a very simple patch which introduce a vim function
jump({count}). :call jump(-5) will jump back in the jump list by
5 positions and :call jump(5) will jump forward five positions.
Any comments are welcome,
Marcin Szamotulski
