The abort character (CTRL-G by default) is special and should not be
rebound. On the IBMPC, the keyboard interrupt 0x09 is hooked and a quit
condition is signaled when it is pressed. For this reason, it should not
be used in any keybindings. A similar statement holds for the other
systems.
This character may be changed using the function set_abort_char
Using this function affects all keymaps. For example, putting the line
set_abort_char (30);
in your jed.rc file will change the abort character from its
current value to 30 which is CTRL-^.
