event types and event IDs are symbols, the data is a float.  The whole  
event is a set of atoms:

[abs abs_x 114(

[key key_q 1(

A set of atoms that begins with a float is defined as a "list" in Pd.   
A set of atoms that begins with a symbol is undefined.  Try out  
hid-help.pd and it will be clearer, there are numerous examples there.
