right click and you should see "delete document" 3/4 way down the menu. If not please post the platform and CS doc. you are trying to delete. Hope this helps.
P.S. if you are just trying to delete pages from a multi-page doc. not possible- whole doc. can be deleted but not parts....
I don't see anything when I right click, but I did find that in the dropdown menu under Review there is an option to Delete Part. This didn't seem like a Review function so I didn't look there at first but it works. Thanks for your help.
you are welcome...diff platforms diff options!
