asterisk users - Oct 2005 - Polycom Button Remapping: Part 2

Thanks to some help from this list, I can remap useless buttons (such as 
services).  However I can only remap to other things that are also 
useless.  So my question is:

Does anyone have more detail on how to use the functions listed in the 
Admin Guide in section 4.6.1.15.  I would like to be able to dial a 
number from these buttons, or perhaps perform a series of key presses, 
but so far I haven't got that working.

Is there some document somewhere that details these functions, or at 
least provides some examples?

Thanks,

Matthew O'Connor
