JavaScript - Detecting keystrokes
iCab doesn't support the key events at all. Many thanks to Hallvord Steen for his summary of the key events in Windows browsers; his page saved me quite a bit of work. Detecting the user's keystrokes turns out to be a rather specialised branch of event handling. This page details some of the more obnoxious problems, and gives the inevitable compatibility table. The first problem is that there is n

JavaScript Madness: Keyboard Events
Note: I have stopped updating this page. At this point nearly all popular browsers are have achieved a good level of compatibility on most of these features, and their behavior with respect to them just isn't changing much anymore. The only thing web designers really need to still watch out for is IE8, which is lingering due to the fact that it is the best version of IE that works on windows XP. (
