Changing resolution of a mesh

When creating an ICO or UV sphere using SHIFT+A, you can press F9 to open up a menu that allows you to define the amount of segments. However, if you switch to sculpt mode to object mode for example, I can’t seem to find a way to change the amount of segments again. Is this possible, perhaps via a keyboard shortcut? Thanks in advance!

I’m an absolute beginner (started today), so apologies if this is a dumb question aha! I couldn’t seem to find a good answer online.

hello no you cant add primitives directly in sculpt mode, only in edit mode and object mode and then you go to sculpt mode…

But if she uses a multiresolution modifier it’s not necessary, is it?

Add a subdivision surface modifier and apply it. (And watch tutorials :grin:)
