VT100 Function Key Sequences
Sequence Description
<ESC>OP Function Key 1 (PF1)
<ESC>OQ Function Key 2 (PF2)
<ESC>OR Function Key 3 (PF3)
<ESC>OS Function Key 4 (PF4)


A VT100 terminal only has four programmable function keys. All other function keys are
undefined, however some applications map the remaining keys using the sequences
for a VT220 terminal.

VT220 Function Key Sequences
Sequence Description
<ESC>OP Function Key 1 (PF1)
<ESC>OQ Function Key 2 (PF2)
<ESC>OR Function Key 3 (PF3)
<ESC>OS Function Key 4 (PF4)
<ESC>[17~ Function Key 6
<ESC>[18~ Function Key 7
<ESC>[19~ Function Key 8
<ESC>[20~ Function Key 9
<ESC>[21~ Function Key 10
<ESC>[22~ Function Key 11
<ESC>[23~ Function Key 12


The first five function keys in the top row on a VT220 are designed for local functions and
are usually not configured so that an application can detect them. In the emulator, F1-F4
are mapped the same as the PF1-PF4 keys on a VT100. The F5 key is left undefined
because there is no direct mapping for this key on a VT220 keyboard. Some applications
may require that the keys be remapped to an alternate sequence.

VT220 Function Key Sequences (Alternate)
Sequence Description
<ESC>[11~ Function Key 1
<ESC>[12~ Function Key 2
<ESC>[13~ Function Key 3
<ESC>[14~ Function Key 4
<ESC>[15~ Function Key 5
<ESC>[17~ Function Key 6
<ESC>[18~ Function Key 7
<ESC>[19~ Function Key 8
<ESC>[20~ Function Key 9
<ESC>[21~ Function Key 10
<ESC>[22~ Function Key 11
<ESC>[23~ Function Key 12
