The cool thing about EditPlus is that it makes scripting in Maya a bit easier. If you go to: https://www.editplus.com/others.html and just do a search for "maya" on the page you'll find a mel support zip file. This allows EditPlus to recognize the .mel suffix....not to mention on the left-hand side gives a maya attribute word list for scripting. When I first came across it, I authored a post in the mel forum and included a screenshot. Here's the link to the thread if ya want to see what it looks like:
