I've set up iTerm2 to map numpad keys to send correct xterm key codes as suggested in this answer. However, I have an issue with the Enter key: all I get is the bell in my shell.
When I try to set up a new key binding and hit the Enter key in the 'Keyboard Shortcut' text field, the symbol is exactly the same as for the Return key (i.e. no num-prefix). The Return key works as expected.
How do I get to send the numeric keypad Enter key to send 0x0D?
