The popup-menu appears after pushing the right mouse button, directly
at the mouse pointer. The separate entries of the menu are placed in
rows beneath eachother. The rows, which end in an arrow, have another
submenu. If you bring the pointer in the vicinity of one of these arrows
the submenu will unfold. Menu entries are selected by releasing the right
mouse button on top of them. Should you want to chose the first entry
in a submenu, it suffices to select the submenu entry in the popup menu.
Two other, slightly different manners of operation of the menu can be set
through the configuration file (see chapter 6).
The menu either always appears slightly to the lower right of the
mouse pointer, or the program remembers the last menu entry which was
selected. After repeated activation of the menu this entry is then
selected immediately. This mode is also the default mode.
