There are some support for the right mouse button click. If the word is a verb a right click makes it possible to switch between active, passive and imperatives and  participles forms. As in this example with the verb δανείζομαι, the Active voice is not available because this verb only exists as passive. 

The third alternative, imperatives etc is not yet fully functional, may contain errors and is not fully tested.

Most list fields are editable and changes will update in the database when you leave the field with the enter button! If you leave the field by other means, such as clicking with the mouse or using the tab there is no update.
