Query: OK, but not great

Just an OK product. Would like to be able to use the Tab key to move around. Sometimes it won't accept the correct letter. Would like it to give the corresponding clue for the across or down function when you're in that grid, but instead you have to scroll up or down the lists. Would also like to it be availabe for a full screen view. Not worth the money as far as I'm concerned.
