How can I select multiple graphics within a text frame?

[Mark]

Hi,
I have imported text in an Indesign CS document.I've placed some graphics in
the document and I'd like to select a group of them and move them at once.
Everytime I try to do that I end up selecting the whole text frame. I can
individually select the graphics using the shift key and then move them as a
group, but that is too time consuming. I'd like to just drag across them and
select them all as a group. How do I do this?
Thanks
