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.

Actually, *I* for one use it -- since you can trigger it by typing Ctrl-break,
I store an oft-used dial sequence in it, then Ctrl-break dials the phone
for me...

Found a copy of the VT100 user's manual, and it sez (page 12):
(paraphrased)
1. place terminal in set up mode B
2. press Shift-A (caps lock won't work here)
   You will see A = on the screen (near lower left).
3. Type a delimiter character (any character you're not gonna use in the
   message itself).  This delimiter character will not be part of the
   answerback message.  If you make a mistake, type the delimiter character
   again and go back to step 2.  No editing can be done, you just have to
   do it all over again.
4. Type in the message.  It can be up to 20 characters long.  Control 
   characters will look like a diamond symbol here.  So does <return>.
   It lets you use a <return> in your message.
5. Type the delimiter character again.  Then the message will disappear
   from the screen.
6. Save it, along with the other set-up settings, by doing Shift-S

To use the answerback: Ctrl-Break.

I used the answerback to store the phone number I dial in with.
It looked like A = xATDT5551234<return>x
                          ^ phony phone number
(The return looked like a diamond symbol, and I didn't get to
see the second x.  Now, I hit Ctrl-Break to dial up.  Thanks to John
above for this idea.
