Re: Text Header/Master Page

If you edit a master page item, while on an actual page, the master page will not be altered.

If you want to change somehting globally (eg: type tracking)on all your pages, you would go to the master page and change the item there, and all your pages will update.

Adobe has done alot of homewotrk when it ocmes to master pages, and they have targeted quality and continuity to take priority. You can even create a new master page B to be based on Master page A. If t a chaneg is done to A, then that change will happen on both A & B (works well and very intelligent). You also have the option to create master pages which are not based on others and independant of each other.
