About 'return' key

Hi all,

In my client/config.cs file has this:
moveMap.bindCmd(keyboard, "escape", "", "escapeFromGame();");

So it means I can do the 'escapeFromGame' function if I pressed 'escape' key.

But when I added this:
moveMap.bind(keyboard, "return", doReturn);
or
moveMap.bindCmd(keyboard, "return", "", "doReturn();");

and pressed 'return' key, it did nothing.

So could some body help me to do this?

Thanks alot.
