I have only seen terminals with 24 Function keys ( There's probably ones with more) but very often the Higher function key numbers could be used for shifted versions of those Keys. So in your case you could have F1 = F1 F13 = Shift F1 F25 = CTL F1 F37 = Alt F1 You can see how 64 could be used up easily enough. The only requirement is that your termcap provide the entries and that the terminal itself can transmit a unique Escaped sequence for each of the keypresses that you want to use. Ah...this takes me back...... DOB. sending to informix-list
