If you have a lot of JavaScript code in your pages

If you have a lot of JavaScript code in your pages, the spell checker will probably go ballistic over the code. It will not recognize your variable or function names unless you've entered them into the spell checker's dictionary, which is a practice I do not endorse.

The solution is to make a copy of your page and remove the contents of the <SCRIPT> element before running the copy through a spell checker. Because you'll be making changes by hand, this should be an iterative process. Of course, you can avoid the iterative process if you have access to software that will merge changes automatically.
