Enhancement: Numpad Enter Support for guiTextEditCtrl

Greetings!
I've discovered that the numpad Enter key is not supported by the guiTextEditCtrl. It can be frustrating to type in a number with the numpad but have to go waaaay over to the keyboard's return key. So, here's how to add that support.
Open up guiTextEditCtrl.cc and go to the onKeyDown() method. Look for the following code:
Now add the following:
And that's it! Enjoy!

case KEY_RETURN:
//first validate
onLoseFirstResponder();
mHistoryDirty = false;Now add the following:
case KEY_RETURN:

onLoseFirstResponder();
mHistoryDirty = false;And that's it! Enjoy!

Question about the coding: does placing the two case expressions together like you show act like an OR?

In that specific example it acts as an "or", but in general, it's more of a "do this, and then do this, and then do this" until you hit the break (or end of the switch).

@Desmond: Yes, in C/C++, if you do not put a break; command at the end of a case body, run flow will "fall through" to the next case. This can be really nifty when you have certain sets of cases that all need a small base of common things to happen, and maybe 1 or 2 unique ones--but it can also be a nightmare when you accidentally forget the break, and can't figure out what is going on.In that specific example it acts as an "or", but in general, it's more of a "do this, and then do this, and then do this" until you hit the break (or end of the switch).

It's sort of parallel to gotos and labels.

Ben's got it. In fact, switch/case just gets translated into a string of simple assembly-language compares and jumps.
