| context always applies to the last selected entry/entries. Thus when |
| the selection is not actual visible, it is not clear to which |
| entry/entries the menu belongs to. In addition, the menu may be |
| opened far away from the selection which it refers to.</P> |
| <P>When rising up the context menu by keyboard (shift-F10), the menu |
| is placed at the actual mouse position and not at the position where |
| the selected entry is/entries are located.</P> |
