I'd be interested in one that's good for entering code or technical
details. I didn't like the CKEditor demo because there was no simple
button to put text in a fixed-width ("code") font, and when typing in
multiple lines of code it put in a paragraph break every time I hit
Return, and you needed multiple controls to get a code box with a
background color or something to make it stand out from the
surrounding text.
All that said, I haven't yet spent the time to find an editor I'm
really happy with, so I should try the other recommendations here.
Thanks,
Aaron
