RE:  TPU/EVE: redefing a key after defining it as a DO key.

Right you are, <do>tpu undefine_key(pf1) does remove an EVE key definition.
What fooled me is that the EVE manual says "to change or cancel a key 
definition, re-define the key".  I should have thought it could have been a 
TPU command... moral of the story:  users of layered software should find 
out what layers lurk below, and then read those manuals too !!
