Comment 674 for bug 263435

"The second passes all key events to both the plugin and the DOM, except for the ones which generates movement events (arrow keys, space, pageup/pagedown...)." What does this mean precisely? In Windowless mode, plugins are supposed to return true/false whether they handled any particular keystroke, and we should only propagate the keystroke if the plugin didn't handle it. This works on Mac, IIRC: does it not work on Windows (at least for the popular plugins)? We can't have arrow keys that move the page around and also do things within the plugin like text navigation or gaming commands.

Are control-t/w/r localized? I suspect they are, and so we can't just hardcode the English letters, but really need the application frontend to tell the plugin which keystrokes are "special". Also, for plugins that install subwindows (Acrobat), does this keystroke hook still work? Or is this primarily for Flash?

jmathies will be the eventual reviewer for this, but I think we should probably break it apart into the windowless and windowed-mode patches, which are pretty different.
