I use Crimson Editor quite a bit when coding, especially PHP. The feature I like most is copy column which will copy a column of text while ignoring the characters to the left and right of the column.
Thanks for the tip. Although I'm pretty happy with Notepad++ (I also use something called Html kit 292 - no longer in active development), I always like giving new editors a try and will definitely give this one a run when I get to work tomorrow.
