In Issue 45945 ("Draw and Presentation split screen view"),
a request was made to restore the "splitting the screen" feature.

OOo 1.1.5 seems to be the last version that
provides this feature in Draw and Impress.
Although later versions of the suite allow it in Calc only,
AOO Help still lists Draw and Impress as having the feature.

4.1.14 HELP topic "Shortcuts (OpenOffice Accessibility)",
section "Controlling the dividing lines" reads:

"Documents of OpenOffice Calc, OpenOffice Draw, and OpenOffice Impress
 can be split horizontally and vertically into separate views.
 Each view can show other parts of the document. Using the mouse,
 you can drag a dividing line from the scrollbar into the document.
 • Shift+Ctrl+F6: shows the dividing lines at default positions
   and focus a line.
 (...)"


To reflect the current state of affairs, the mention of Draw and Impress
should be removed from or commmented out in the Help source file.

NOTE:
The Shift+Ctrl+F6 keyboard shortcut (Shift+Command+F6 on Mac)
belongs to the "reserved keys" category. As non-configurable,
it is greyed out in the Customize dialog for the suite and
for any of its components.
