It's my fist message to the list so I hope I'm not missing anything. In section 10.4 "Commands in the agenda buffer" the View/Go to Org file commands are described as:
@tsubheading{View/Go to Org file} @item mouse-3 @itemx @key{SPC} Display the original location of the item in another window. With prefix arg, make sure that the entire entry is made visible in the outline, not only the heading. @c @itemx @key{TAB} Go to the original location of the item in another window. Under Emacs 22, @kbd{mouse-1} will also work for this. @c @itemx @key{RET} Go to the original location of the item and delete other windows. @c According to the Texinfo documentation: https://www.gnu.org/software/texinfo/manual/texinfo/html_node/_0040itemx.html It seems like: @itemx @key{TAB} and @itemx @key{RET} are not subsequent entries of @item mouse-3 but entries on their own. They should be coded as @item. Jean-Christophe Helary
