Kicking off
I'm a big fan of Konfabulator. From their Workshop section they have a tutorial and reference guide.
BTW I agree with Alexis Sayle: anyone who uses the term "workshop" except in a light engineering concept, is a wanker.
Anyway, they're very good guides.
The tutorial recommends a couple of basic editors. I chose Note Tab Light because it's free. But I find that I could have chosen it because it's very good.
For years I've written HTML and .bat files using nothing more sophisticated than Windows' Notepad.exe - hardcore you see. But Note Tab Light is very good indeed.
