I use a Win7 machine at home, and do my Clojure work with Notepad++ and an open command prompt. Most of the time I’m in the REPL, and I get to this via leiningen. It’s not the most elegant way to do things (I believe that would involve Emacs), but it ain’t bad.
I was just now tapping at the REPL and wanted to go back a few characters while writing out a function call. Absentmindedly, I used the Emacs keystroke CTRL-b, and bloody hell it worked. So did CTRL-f and CTRL-e.
Wow. Considering that I’m sitting on my couch with my laptop where it belongs (on top of my lap), I’m thrilled that I don’t have to get all uncomfortable finding the arrow keys when editing in-line. Woo!
