How do you redefine shape defaults for Keynote 6?
I tried using a blank slide, setting the shape (red outline circle etc) selected the shape, went to Format, Advance, and found no good options either as described in the manual or anywhere else. thanks.
Actually, I misread you. It IS possible to save new presets from the same menus (simplest way is to hit the plus sign, create a new style, reformat it, and it is saved). That is equivalent to customizing the defaults. Color, line width, etc. can be changed and saved for later use; various styles can be added or deleted (but there is no easy way to move a style to the head of a list except by deleting and recreating as needed)
