When adding data in the data editor, it is extremely inefficient to have to go
to the data menu everytime you want to add a row. hitting enter at the last
column,row should create a new row so more data can be entered. Ctrl-I is not
the standard way of doing this. also, if you are at the last (column, row) and
you hit enter to enter the data, the selection box is moved to (1,1) so if you
then hit ctrl-I, you insert a row after row 1.

When a cell is highlighted and you start typing, it should overwrite whatever
is in the box, not append to it. ctrl-tab should do the opposite of tab (make
the selection go backwards). unfortunately, i think this needs to be made more
excel like to get people to use it. Excel is a pretty efficient as a data
entry app. as this screen is now, I don't think anyone could use it to enter
more than a few rows of new data, although it should still be usable as a data
editor.
