  We address the issue of slow-roll in string theory models of inflation. Using
a K\"{a}hler transformation and results from the D3-D7 model, we show why we
expect flat directions to be present and slow-roll to be possible in general.
We connect with earlier discussions of shift symmetry for $T^6/Z_2$ and
$K3\times T^2/Z_2$ compactifications. We also collect various contributions to
the inflationary potential and discuss their importance for slow-roll. We
include a few simple checks of the form of the Kahler potential on $T^6/Z_2$
using T-duality.
