[TxMt] Can I bind numeric keypad keys?

[Stuart Hungerford]

Hi,

My reading of the TextMate blog entry on keybinding for switchers
leads me to think I can bind (say) the numeric keypad "enter"
key with:

{
     "#\U0003" = "moveToBeginningOfLine:";
}

In the appropriate .dict file.  Unfortunately that doesn't seem
to work.

Are there other issues in binding numeric keypad keys?  Apologies
if this is a stupid question: I'm a complete OS/X neophyte.
