The Flash text and other options were deprecated in CS4/5. Basically it's not good practice to keep using them because they are not compatible with mobile devices and there is a push to move away from Flash to HTML5 for animations. And for dynamic menus, CSS has picked up much of the slack. You can insert an SWF object by going to Insert->Media SWF. But if it's for a menu you should look into a solution from Project Seven or any CSS menu (there are a ton if you Google search CSS Menu generator).
