    Thanks will file this list away for reference 🙂 Wonder how it differs from normal keycodes.

    Any idea about the “special” keys like next, undo, redo, cut, paste, etc?
    Some like undo, redo, paste don’t seem to generate any keydown/keypress events (detectable by JavaScript) at all even tho they change the contents of the form input field!

    “Undo”, “Next”, etc. aren’t keyboard keys, so they’re not represented. If you’re concerned about the input fields changing, then add an onchange handler. But in general, these are keys “beyond” the realm of the web page.

    Yeah, unfortunately the change event isnt fired until the user leaves the field…I need to react immediately to implement “type-ahead” like features…UNDO/REDO/PASTE break the ability to do that since there is no event to react to until some arbitrarily later event like blur or the user getting around to typing the next normal key. 🙁

    Hi Bruce, Eric, do you have a solution to your paste problem? I have got the same problem, since I have to restrict a textarea by the number of lines dynamically via event handling in Javaascript. This works on all browsers, since I am listening on keyup event. But unfortunately this does not work on the iPhone/iPad.
    The only “solution” that came to my mind was to implement a dirty “setTimeout” listener that checks for changes of the contents every few milliseconds. But this is really dirty …
