What is your text editor of choice?

For GUI: gedit For CLUI: vi

In the console, I use nano (never liked vi/emacs) - simple, effective and universal.

In X, I find KATE's Sessions feature invaluable to have lots of projects open, each with its own set of files. So I can have, say, one session called "Comp" containing my computer-related files, "Web" has my website HTML files, "Scripts" has all my BASH scripts, "Music" containing my musical text files, "Songs" has my songs, "Poems" likewise, "Acc" for my financial accounts, etc. Syntax highlighting and standardised key bindings (even a VI Mode if you prefer) make KATE very easy to use,

Emacs all around - except for when I have to work on some PHP code.

gedit, simple and easy to use. Great job.

I've settled on emacs. The more you use it, the more you can customize it. I also use it as my email client.

My favorite is nano.

I prefer nano, because can use it everywhere,because it's distributed with most linux distros and it's simple ;)

cli and full feature : vim
cli and lightweight : nano
gui and almost full feature : Gedit
gui and lightweight : Leafpad

I've found kate to be pretty kewl ;) and bluefish is pretty good too when you need a little hybridization between just a text editor and an IDE.

But I still end up using pico or vim more often than not to quickly get into a file and do something quickly and get out.

You just can't beat the text based editors when you know exactly what you want, and need to get it done fast.

vi is a good text editor. Comes bundled with any Unix or *nix clone and has tons of features. In case you are not used to basics of vi, get used to it, it's really beneficial.
