Question

What is the HEX sequence for CRTL-UP key-press?
For example for UP – ‘0x1b, 0x5b, 0x41’.

Answer 1

I wrote a simple Python 3 script to find out the answer:

while True:
    print(" ".join("{:x}".format(ord(x)) for x in input()))

I had to turn off the standard “Mission control” shortcut for the CtrlUp keystroke, but after doing that I get the following in iTerm2:

$ python3 test.py
^[[A
1b 5b 41
^[[1;5A
1b 5b 31 3b 35 41

The first two lines represent an Up keypress, while the second two lines represent a CtrlUp. You can use this same program to find out the character sequences for any other keystrokes.
