In the case of a key repeat, you should generate multiple keydown/textInput/keyup, and not just the textInput. That's exactly what the repeat functionality is about. It does have the drawback of not having the ability to differentiate between fast key input from a user on a keyboard and the key repeat functionality. > The bigger problem, however, is that it is impossible to detect key > repeating for characters whose purpose is something other than > generating text, since textInput events do not fire.

Shouldn't this be handled by the accessibility preferences of the operating system? Philippe
