Analyze References window
Ctrl+Alt+Y
ReSharper_OptimizeReferences
The Analyze references window is used to display project references when you invoke the Optimize References command. It displays unused assembly references, used assembly references with corresponding usages and pinned references.
Window tabs
When results of the Optimize references command open in the window, they are displayed in new tabs, which show up on the left. The previously open tabs move to the right if the width of the window allows, otherwise they unload themselves saving memory - but you can always restore them by clicking the arrow that appears to the right of the tabs and clicking the required tab:
To prevent a tab from unloading, click the pin icon 
next to the tab title.
