I am new in InDesign. For Book & Newspaper I worked QuarkXpress. But Now I want work in InDesign. I make a master page in InDesign, But when I view normal page my design is not editable because everything is locked. I want know why object is locked. And how i edit master pages matter to normal pages?
Hold down "Command+Shift" on a Mac OS, or "Ctrl+Shift" on a PC, and click the item on the "normal page" that you want to unlock. Once you click it, the item is released from the Master Page and can be edited or deleted. A typical example is deleting page numbers from certain pages.
I would add here that the only objects that should appear on your master page(s) are those that never change from page to page. Any content that you need to change for each page doesn't belong on a master.
