问题 I am simply trying to take a KeyCode and a modifier mask and convert it to a KeySym using the Xkb extension. I cant seem to figure out why this doesn't work. Its obvious that the modifiers dont match but I dont know why.

阅读更多关于 How to catch event.keyCode and change it to another keyCode?

问题 I have checked other questions here at SO, however they do not answer my question. I want to simply catch certain keyCode and replace it with another.

But you can replace those keyCodes with your (eg. when capital "A" is pressed, it should replace with zero 0, etc.). The idea is to replace the keyCode. phrase.keypress(function(event) { if (event.shiftKey) { switch (event.keyCode) {

问题 I am using a windows 8 laptop. My old laptop had a key combo, fn+f5, which would make the computer go to sleep.
