I'm not sure that the widget should win, actually. Changing the user interface locally is not exactly kind to the user, because of its unpredictability, poor discoverability, and difficulty to learn. >> Are these combinations going to be OS and browser specific? The reason why I suggest using the actual accesskey mechanism in HTML rather than directly trapping key events is that accesskey *can* be implemented not to clash. My proposal to the HTML WG to improve the specification of accesskey would make it clearer that accesskeys can be remapped by the client, according to what is available. Thus you get (at least) the ability to re-use existing techniques - and while there are known hassles with gobbling accesskeys out of the UI in Internet Explorer, Opera doesn't have the problem already, Firefox is changing. > Not sure if this helps any, but my list of reserved keystrokes, while now > over 5 years old, is still pretty-much up-to-date.
