Temporary input mode

If you want to implement something global, independent with input method, for example, press "Ctrl+Shift+Alt+U" and type hexcode to input Unicode character, then what you want to do is something we called "Temporary input mode". It works just like a input method, but it only provides limited function for special use. In this case, we need to care about "Pre-Filter". As you can see, "Pre-Filter" can filter the key before it goes into real input method, so we simply process everything here.
