In kpresenter (and kword docs), the behaviour of flattening toolbars do not match with the described behavior :
Clicking on the toolbar handle results in that toolbar being 
<quote>flattened</quote> so that you have some extra space for viewing the 
main editing window:
=>No, this makes nothing.
(needs right click-Orientation-flatten)
(If you 
<mousebutton>right</mousebutton> click on the handle of a hidden toolbar, 
this item appears as <guimenuitem>Unflat</guimenuitem> instead.)
=>Makes nothing.
Needs left click.

Or perhaps the problem is this function is broken ?
