Great Firefox extension.
Xinha Here allows you to right click on any textarea in a page and select Xinha Here to fire up a nice WYSIWYG HTML editor in a separate window. Bolding, italics, bulleted lists, links, images, etc. are all supported and there are keyboard shortcuts in addition to toolbar icons. Do your editing as you see fit and then when you hit OK, the corresponding HTML is pasted into the textarea (unfortunately, it seems to get paste in as one long line, it would be nice if it broke my bullet lists on to separate lines, but oh well…maybe the next version).
This is a great way for me to get WYSIWYG editing for my blog postings without having to use a WordPress 2.0 beta (which may not be stable or might have security issues) and I get this WYSIWYG editing capability for other uses too.
Great stuff.
