microsoft.public.windowsxp.customize

I need to enter a number of times in this form:

HH:MM

And I would like to use my USB numberpad with my notebook to do this. I
would like to remap the number pad's "." key to be a ":" instead.

I have KeyTweak, and also know other ways of remapping the KEY, but this
would only do this mapping:

Numpad "." ---> ";"

(requiring the shift to gain the colon.)

Is there any way for me to do this?

Thanks
