 A property value can be modified in the field at the bottom. New values always require an extra validation.
 New properties can be added or removed:
 
-- <img src="{%include icurl%}other/textfield_delete.png" class="tlbric"/>: Removes the selected property. Note that the effect is not reflected until the project is saved as a file (since Coedit does not communicate directly with DUB).
 - <img src="{%include icurl%}other/textfield_add.png" class="tlbric"/>: Shows a small dialog that allows to add a new value, a new array or a new object.
