Coding in notepad or nano has been a great investment of my time.

I don't need to learn any of these tools or read about any drama, I just type letters into the screen and use my keyboard to move my pointer. That's it, if I need anything more complex to handle my codestring, I write code.

But I have never needed to run a search and replace of a variable, both notepad and nano can do that. If I need anything more complex I do it manually. Anyone that does some exercise or has had a physical job knows that doing something 26 times in a row is basic stuff of any worthwile endeavor.
