XGrabKeyboard. There's also a whole section on security in man xterm, sorry, forgot about it before. But it's no magic bullet. Suddenly, your window manager hotkeys stop working, so you can't really have a default current window grabs keyboard policy. Your screensaver also needs to grab the keyboard. So if your browser only grabs the keyboard while entering a password field, that essentially means the screen locker will never activate in that state. Rare, but totally confusing to users.
