Okay, so I've recently realized the correspondence between Control keystrokes and ASCII control codes, e.g. ^D sends the EOT character because EOT is ASCII code 4 and D is the fourth letter in the alphabet. I'm wondering what would be the keystrokes for characters beyond 26 decimal, i.e. ESC, FS, GS, RS, and US. Does the Escape key send the ESC character? What about the default ^] keystroke in Telnet that escapes to the shell. Does that send the ESC character?
And I apologize if this is off-topic. I couldn't find anywhere else to put it.
