The modes
(most right)Here you can see in what mode you're currently working
in. This can be either "Edit mode" or "Text mode". If you are working in "Text
mode" (you've pressed the 'A' or selected text-on see also:
The text-toolbar) you won't have access to the
popupmenus, and you can consequently not edit move or remove elements
Please
don't forget to exit this mode if you're through with text writing. If you
want to re-edit a text-element you'll end up in this mode
automatically. Standardly you're in edit-mode.
