Good news for you Internet Explorer wackos: the Instruction Reference should now work for you. I switched from DOM methods to innerHTML. The Instruction Reference should be as a whole much faster regardless of which browser you use. My only reservation is that innerHTML is not a W3C standard and does not have a completely certain behavior.
At some point I'm going to switch the Instruction Reference over to using JSON instead of XML. It should make it that much faster, since JSON can be parsed easily with eval() and accessed much easier.
Update: I've switched over to JSON already. The file size is a little smaller, and the Ajax GET (generation of the instruction database in JSON plus the download time) is around 40 to 50 milliseconds faster now.
