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:
<
You may want to use Vim global marks.
This way you can quickly bounce between files, and even to the marked location in the file. Also, the key commands are short:
'C
takes me to the code I'm working with,
'T
takes me to the unit test I'm working with.
When you change places, resetting the marks is quick too:
mC
marks the new code spot,
mT
marks the new test spot.
