Idea Summary
Suggest creating a new shortcut that would allow developers to quickly cycle through page items.

Use Case
When editing page items, it is useful to PIN attributes, so that I can lock in on a certain attribute that I need to edit across different items, but then have to click through the different items I want to edit.  Being able to use a shortcut would help us move from item to item to edit more quickly. 

Preferred Solution (Optional)
Ctrl+Alt+Page Up/Page Down
