Ctrl+Alt+Shift+B (in Lightroom Classic CC 8.2 for Windows 10) to set as target collection is not working for me. I can set the same collection as the target collection without any problems. I know that smart collections cannot be target collections; the collection does not have the little gear by it. It is a collection, not a collection set. I can set it as a target collection by selecting it and clicking on the "set as target collection" menu item. Then the + sign appears by the collection. But I should be able to select the collection and press ctrl+alt+shift+B to do the same thing. Do I have to press the keys all at the same time rather than pressing and holding until all have been pressed?
