I\'ve started using Vim to develop Perl scripts and am starting to find it very powerful.
One thing I like is to be able to open multiple files at once with:
<
In my and other many vim users, the best option is to,
:e file_name.extension
And then just Ctrl + 6 to change to the last buffer. Or, you can always press
:ls to list the buffer and then change the buffer using b followed by the buffer number.
:vsp for vertical split
:sp for horizantal split
And then to change the working split.
You can ofcourse edit any file in any number of splits.
