I too am interested. I use Notepad++ as well. I've heard of other free text editors like Bluefish and Komodo Edit, but I still haven't found one I particularly like.

I've just downloaded conTEXT. Bearing in mind i've only used it for a few minutes, I have to say it appears more usable than notepad++, It has some nice features, presented simply.

Thumbs up so far! Thanks Ian.

I've tried more than 30 text editors on Win 7 so far, Sublime Text is a real fun to use, so flexible, not as pro as Notepad++ though...
TopStyle 4 is awesome, just a super pro.
Programmer's Notepad is simple but powerful.
Komodo IDE is also my fav.
So I've got 4, that I prefer to use whenever I feel like...

Notepad ++ is what I use, free and supports a variety of languages.

I also found Microsoft WebMatrix's text editor a very helpful and powerful way to type more rapidly, more organized and more secured. You guys should check that out if you haven't yet... It's free, it's good to experience that. WebMatrix is a server too... and has WordPress installed in it. This is the download page http://www.microsoft.com/web/webmatrix/ and this is a review video by Microsoft itself http://channel9.msdn.com/Blogs/Dan/Simon-Calvert--Scott-Hunter-WebMatrix-and-the-new-Razor-Syntax

But I still prefer keep things simple, using Wamp and a simple text editor that help me go speedy.

i know that the question was geared toward a free program, but i have to go with Expression Web 3 and here is why; WYSISWG features aside, the code is color coded which is nice sometimes if you have inherited a project that was not commeted correctly, plus it is a smart text editor where it will finish words for you i.e, if i am typing the word "padding", it gives me a list of padding atributes that i can choose from. EW aslo has a built in FTP program and has a Super Preview feature that works alot like FireFox's Firebug but works like that in all browers and allows for a side by side comparison.

I know that some of these features come with other software, but is seems to be a nice little bundle of stuff i use all the time. Just my 2 cents...

@JoshWhite thanks for that, it looks awesome. I'm going to give it a try.

Hmmm too many options! lol

Since I just bought a macbook pro I've been trying to find what I could use in both environments.

Windows my tools are notepad++(first choice its just straight text and plugins are nice) and also I use eclipse with the aptana extension or just download aptana. (php, RoR)

If your stepping into .net stuff VS 2010 express is great, I use VS 08/10 at work I enjoy the library extensions for languages and code completion is helpful.

You want just a sweet editor? Sublime text ver 2 alpha just came out and its pretty awesome, it's almost identical in the sense of textmate and E editor....

I vote for Notepad++ , because its very lightweight man....

zencoding(autocompletes like TextMate) works well here and it saves you more time...in coding html/css

you can zoom well the code using the mouse control

Syntax coloring are good...

some seperate windows for code reviewing...

and lol Notepadd++ is too easy to use

the only thing I wish for notepadd++ , is to support SASS/LESS syntax

zencoding is almost avaible for every editor: http://code.google.com/p/zen-coding/
Personally I like Coda best, but for windows I prefer Sublime Text 2 due to Coda being Mac only

I started with HTMLKit. Have tried Notepad ++, SublimeText, and many others. But maybe because I've gotten most familiar with HTMLKit, that's what I find easiest to use. I really couldn't get comfortable with Notepad ++ and the others I tried.

For me most of HTMLKit's features are helpful, and I can turn off those features I find inconvenient or inefficient (for example, I don't like how the autocomplete feature handles a href).

I recently customized the colors so that the things I want to stand out are clear, while those that are less important to pinpoint are more muted. This has really helped.
