I configured it to use spaces instead of tabs. I added a shell command to run perltidy over the current selection with a command of 'perltidy -st -se' command input of 'either', command output to 'same document', and selected 'output replaces input'. I have .perltidyrc set up to my taste.

I have another shell command to do 'perl -c' with command input of 'either'. That's not so much a PBP thing as it is simply a 'nedit as an IDE' kind of thing.

I use nedit extensively at work on Solaris boxes and on my workstation under Cygwin. Right handy, I find. At home, I use BBedit.
