In the rest of the free space, the pony select in the list is centered. You can move
the pony, in case it is too big, by using the arrows keys with @kbd{control} held down,
or using the @kbd{W}, @kbd{A}, @kbd{S}, @kbd{D} keys (for QWERTY and QWERTZ layout,)
or with the @kbd{<} (or @kbd{Ä}), @kbd{A}, @kbd{O}, @kbd{E} keys (for Dvorak and
Svorak layout.)
or with the @kbd{<} (or @kbd{Ä}), @kbd{A}, @kbd{O}, @kbd{E} keys (for Dvorak and Svorak
layout.) To recenter the pony press @kbd{C-l} (@kb{dl} with @kbd{control} held down.)
Browse between ponies using the arrow keys or with @kbd{C-n} (n with control held down)
and @kbd{C-p}, for next pony and previous pony, respectivily. Additionally, @kbd{Q} can
be used list quotes for pony, and @kbd{I} for metadata.

The tool can be exited using the key combinations @kbd{C-q} or @kbd{C-x C-c}.
