If you’re using WordPress for blogging, then you should check out the plugin CKEditor for WordPress. There’s a nice demo of what it looks like…

Regarding spelling, CKEditor has its own spell checker and also SCAYT. However, some bloggers may prefer to use the browser‘s embedded spell checker. For example, I use the “English & Greek” dictionary with Firefox, which really saves time as it checks spelling in two languages at once.

In order to be able to use the functionality of the embedded spell checker, you need two things: re-enable the embedded spell checker, which is disabled by default after CKEditor’s installation and then re-enable the browser’s original right-click context menu. That’s how you do it:

1. Goto CKEditor settings, in wp-admin
2. Goto “File Editor” option on the menu on the left.
3. Make sure you’re editing “ckeditor.config.js”
4. Goto the end of the file and add the following two lines, after the existing text.
5. Save, done!

CKEDITOR.config.disableNativeSpellChecker = false;
CKEDITOR.config.browserContextMenuOnCtrl = true;

Now, a red curly line will appear every time the embedded dictionary does not recognize a word you type. With right-click, you see CKEditor’s context menu. With ctrl-right-click, you see the browser’s context menu, which includes correction suggestions!!
