following the News  or Lars' Blog , I try to use the feature to
hide all Toolbars.
I downloaded a fresh Eclipse for Java Developers build 20160613-180.
However, in Quickaccess I do not see the command
"Toggle visibility of the window toolbars"  or "Toggle Visibility of
all Toolbars" .
I only see "Toggle Full Screen", which does something else (maximize the
whole window) or "Toggle Main Toolbar Visibility", which only hides the
main toolbar but not any view stacks that were minimized as described in
"If you minimize a stack after you selected this command, the minimized
stack will be visible until you trigger the command to hide the toolbars
again. This allows you to decide which minimized stacks are currently
useful for you." 
So how do I use this new feature? Or was it changed/renamed?
