I don't know if you know vim so this might be verbose.

To make a vertical split, run the command :vs
To open vim with a vertical split: vim -O file1 file2
(That is a literal colon, v, and s and an uppercase letter O)

To make a horizontal split, run the command :sp
To open vim with a vertical split: vim -o file1 file2
(That is a literal colon, s, and p and an lowercase letter O)

To resize (when it works) just left click on the separator and drag.
Much like resizeable frames in a web page or a Windows window border
(but you don't get the double ended arrow cursor)

And to close a window in vim, the command is :q
To close all windows, :qall

The easiest way is probably to open vim with a split, it is one command
that can go in the history.

I do have the "void" middle mouse option but I have been running that
ever since I wrote the original patch and attached it to the Google code
issue about it and it was working fine until I updated and used the
mintty provided by your package.  I did remove minttyrc from my home
directory so that the defaults would be used just in case it was being
confused by my settings.  My right click option should be default, show

P.S.  Why does this list not set the "reply to" address to itself.  I am
sending this again because I just realised that I sent it directly
rather than to the list.
