Motivation
I’m in a document. Looking for another item in document. Open Item Finder, but there are way too many matches!
Just like the Find feature, we need to make a distinction between document scope vs global scope.
Proposed Solution
Hitting Cmd-Shift-O opens item finder in document scope. Hitting Cmd-Shift-O when the item finder is open toggles between document scope and global scope. A simple tool-tip can be added to the item finder to tell users about this. The design is a common pattern used in IDEs, etc.
