Browsing German translation

Translators: Orca has a number of commands that override the default
behavior within an application. For instance, on a web page, "h" moves
you to the next heading. What should happen when you press an "h" in
an entry on a web page depends: If you want to resume reading content,
"h" should move to the next heading; if you want to enter text, "h"
should not not move you to the next heading. Similarly, if you are
at the bottom of an entry and press Down arrow, should you leave the
entry? Again, it depends on if you want to resume reading content or
if you are editing the text in the entry. Because Orca doesn't know
what you want to do, it has two modes: In browse mode, Orca treats
key presses as commands to read the content; in focus mode, Orca treats
key presses as something that should be handled by the focused widget.
This string is associated with the Orca command to manually switch
between these two modes.
