This application is basic yet very powerful, and perfect for both inexperienced and more advanced users.
It includes keyboard shortcuts for most of its options. Apart from that, once you finish debugging the code, you can run a simulation to see the final result.
It comes with an comprehensive manual in HTML format to help you get started with DzSoft Perl Editor more easily – or at least it will help if you can read English, since that's the only language it comes in.
The trial version only lets you edit the first 120 lines of code.
