VS 2017's new "Go to All" (Ctrl + T or Ctrl + ,) does not lists items for me.
Searched for a setting for it, no luck. Also no error messages regarding this at all.
Why is this happening, and how can I get the behaviour I expect?
I encountered this issue as well. Somehow I had collapsed the list. If you hover over the point in the picture below you should get a resize handle. Grab it and pull it down to get your list back.
