Sublime Text 3, iTerm
or just write me PM, and I will help you.
I haddn't heard of iTerm, I have the mac ported version of Terminator (which I love for linux) but it doesn't do all the cool stuff on Mac. Are you using iTerm 2 or iTerm? I went to the site and they said the project was on hold and to look at iTerm2 which seems to be a fork.
Has anyone tried Vim on Mac? That's all I use for text editing on Linux and when I was reading this thread it occurred to me that it was probably available for OSX too!
