Hi all,

According to the manual:
https://www.gnu.org/software/screen/manual/html_node/Focus.html#Focus

"(C-a <Tab>)
    Move the input focus to the next region. This is done in a cyclic way so
that the top region is selected after the bottom one. If no subcommand is
given it defaults to `down'. `up' cycles in the opposite order, `top' and
`bottom' go to the top and bottom region respectively. Useful bindings are (j
and k as in vi)
              bind j focus down
              bind k focus up
              bind t focus top
              bind b focus bottom"

I've bound "C-a p" to "focus up" and "C-a n" to "focus down"... And they do
exactly what is said: they switch to the top/bottom region, but NEVER to the
region on the right or on the left and they never go back to an lower/upper
region.
On the contrary, the default C-a <Tab> focuses alternatively on each region of
the whole list of regions, going up/down/top/bottom if necessary and cycling
through the list...

As a conclusion, that means that, contrarily to what the documentation says:
1. "focus <argument>" does not follow a cycle process;
2. "focus" with no argument does not behave by default as "focus down"...

So either the documentation or the implementation is wrong...

This is particularly annoying, since I'm trying to bind a key to a command
that would cycle through the whole list of regions, but in reverse order (in
order not to have to go through a cycle of X (>>2) "C-a <Tab>" to reach the
previous region), but such a command actually doesn't exist :[

Cheers

GM
