in reply to Vim for Perl developers

I liked your article very much. But here at the university we have only version 5.6. So I have to try which of your tips work here.

I also found a misprint:

Vim support both vertical and horizontal window splitting. To split current window horizontally execute ":split" while in the normal mode. To split current window horizontally, use ":vsplit" instead.
I think you mean vertically in the second sentence.
