The key last pressed in the figure is given by its CurrentCharacter property, which can be obtain by:
key = get(h_fig, 'CurrentCharacter');
where h_fig is a handle to your figure.
Is this of any help? Otherwise I suppose we need some more information.

When you turn on zoom mode, it overrides the figure WindowKeyPressFcn . In versions before R2014b it was possible to trick MATLAB to be able to have a WindowKeyPressFcn callback active at the same time as you were in zoom mode, but I am told that as of R2014b that method does not work.
