how to scroll through autocompleted text?

[Anthony DiSante <theant nodivisions com>]

When typing some text into a cell in a worksheet where a previous cell 
already contains the same text, that previous text automatically shows up in 
the new cell, so you just have to type the first few letters and then press 
Enter.

However, if there are multiple previous cells containing similar but 
slightly different text, then the one that autocomplete chooses (which I 
think is just the most recent one) may not be the one you want for the new 
cell.  As you type more, it will eventually choose the right one, but in MS 
Excel, you can simply press Tab after entering the first few characters, and 
it'll scroll through all the matching cells so you can choose the right one 
without having to type out most of it.

Is it possible to do the same thing in Gnumeric?  If so, how?  (Tab doesn't 
do it.)

Thanks,
