Escape key to exit icl

[plainas]

Hey Mathew.

Yes, that is where it is.
The terminal needs to be restored to previous state like it's done on line 127 onwards.

if you do implement it, pull requests are welcome.

Probably time to wrap terminal restoration into a funciton since it will already be used in three different places.
