See below for what happens for me when I hit escape :)

As to the delay, the ncurses man page mentions this in its environment
variables section:

 ESCDELAY
 Specifies  the total time, in milliseconds, for which ncurses will     
 await a character sequence, e.g., a  function key.   The  default  
 value, 1000 milliseconds, is enough for most uses.  However, it is     
 made a variable to accommodate unusual applications.

Hitting backspace generates this in the log:

Control#dispatch:  Unknown event occured
ncurses-event = 263

ctrl-h generates the same... :/

Given that in control.rb, lines 217-218:

Sorry, I forgot the word "scrolling" - scrolling by a single line is
quite slow, but it is the same speed as scrolling by a page so I
imagine it can be sped up in the future. It wasn't really a big thing,
just thought I'd mention it:)
