VT100 PF keys are not programmable in that you cannot make them transmit
arbitrary character sequences.  What a VT100 PF key sends will always be
a fixed sequence (the exact sequence depends on which of four modes the
VT100 is in at the time).  Whatever "programmability" there is is due
entirely to flexibility provided in the application handling these
specific input escape sequences.

"Here is" is an old teletypewriter feature: in response to a received
"who are you" code (value 5 if I recall correctly), certain equipment
models would trigger a 20-character drum that would send out up to 20
character codes in sequence.  The intention was for news wire services
etc. to verify the station they were transmitting to by sending a WRU
code and getting the here-is ident sent back to be printed on the
enquiring end.  The VT100 lets you program this "answerback code"
in SET-UP mode by, I think, Ctrl-A then a delimiter then the ident then
another delimiter (or something like that).  If it were really important
I could look it up, but odds are that you really don't want to use it.
