>Description:
	In ncurses applications, namely MC with TERM=screen 'End' button
	doesn't produce any effect.

>How-To-Repeat:
	Compile latest MC from the ports with ncurses and run it under
	'screen'. Press 'End' button - nothing happens, you can't teach MC
	this button either.

>Fix:
	I thought about it as some bug in ncurses, until I came across:
	
	http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=92215
	
	Date: Fri, 30 Mar 2001 16:48:13 UTC
	Severity: normal
	Found in versions 5.2.20010318-1, 5.2.20020112a-8
	
	> The problem is that kll is defined to be the same value as
	> kend, and (apparently) ncurses checks kll before kend...
	
	Although, it is related to the terminfo, apparently, our termcap
	was generated from the same source, as it contains:
	
	SC|screen|VT 100/ANSI X3.64 virtual terminal:\
	....
	:kh=\E[1~:kI=\E[2~:kD=\E[3~:kH=\E[4~:@7=\E[4~:kP=\E[5~:\
	
	Where:
	
	key_ll   kll        kH        lower-left key (home down)
	key_end  kend       @7        end key
	
	I'd suggest to use the same approach as Debian used, as kH seems
	close to non-existing, when End key is quite frequent and usefull.

	With regards,
	Timur.
