So as I said there is no way to switch to 10-20 in SPM. You can use
the Zoom button to focus on two (consecutive) channels in the
reviewing tool but if you then scroll in time it will return to
displaying all channels. Alternatively you can just use Montage to
make a dataset with just those two channels and look at them. This is
a little bit cumbersome but the reviewing tool in SPM only provides
basic functionality as our focus is on the analysis methods.
