Description David Balažic 2000-08-25 08:29:49 UTC 
There is a documentation bug in the screen man page.
( screen 3.9.5-11 from RC1 )
It says that the termcap codes F1 and F2 are translated to
^[[22~ and ^[[23~ , but both the actual behavior and the screen
entry in /etc/termcap say ^[[23~ and ^[[24~
Comment 1 Crutcher Dunnavant 2001-06-26 20:24:08 UTC 
yep, it is. Will investigate.
Comment 2 David Balažic 2001-07-26 10:34:07 UTC 
same in screen-3.9.9-1 ( and also in 3.9.9-2 )
Comment 3 Phil Copeland 2002-08-12 18:02:07 UTC 
F1 = ^[[[A 
F2 = ^[[[B

Best way to find out is to press <ctrl-V> (capital V) then strike F1
Some will say ^[OP others ^[[A. It depends on your terminal type so the
information isn't wrong per se, it's simply neglecting to opint out that it's
terminal enviroment specific.

Comment 4 David Balažic 2002-08-12 19:53:50 UTC 
There is reality and there is documentation, whose purpose is to describe 
reality. In the case of sceen man page , it fails to do that.
Here is the fix :
< F1     ^[[22~
< F2     ^[[23~
> F1     ^[[23~
> F2     ^[[24~

About your message , Phil :
> F1 = ^[[[A 
> F2 = ^[[[B

On some terminal types, maybe , in TERM=screen not

> Best way to find out is ...

There is nothing to find out. I stated all the relevant facts in my first 
message.

No it is not. The code for F1 is _always_
translated to "^[[23~" ( and F2 to "^[[24~" ),
independent of the physical terminal type.
Comment 5 David Balažic 2002-08-12 19:55:52 UTC 
As this is a clear case of documentation bug ( it says ^[[22~,
when in reality it is ^[[23~ ), I am reopening this bug.
Comment 6 Phil Copeland 2002-08-12 20:24:11 UTC 
The current screen man page is correct (3.9.11-8)

       Function key 10       k;          stuff \033[21~
       Function key 11       F1          stuff \033[23~
       Function key 12       F2          stuff \033[24~
       Home                  kh          stuff \033[1~
