[John Landmesser]

Delphi 2010 Pro:

Per default property Keyoptions is empty and nothing  happens pressing 
insert, delete ...

You can only select the value and edit it.

If property keyoptions is [keyEdit,keyAdd,keyDelete,keyUnique] and you 
press Control plus keyDelete, the whole line is deleted. Doesn't matter 
which column is selected!

YES !!!

keyDelete can  be set, even if keyedit is false !

No !
You just hit the insert key and get ONE new row next to current row.
