With this menu-point you see all entered permanent entries.

You can change the entry by doing a double-click on it. Then 
you get a window, which looks like the window to enter a 
new permanent-entry.

After marking an entry with a single click, you can delete it
with "Delete" from the "Edit"-menu. Or with the "DEL"-key.

If you want to print the list, you must choose the point 
"Print" in the menu "File".
