Is there anyway to click on tags in the tag browser and have them added to the search with the "and" keyword instead of "or"?

Both Shift and Ctrl keyboard shortcuts set them as "or".

The Calibre manual only mentioned Ctrl and Shift:

If you hold down the Ctrl or Shift keys and click on multiple items, then restrictions based on multiple items are created. For example you could hold Ctrl and click on the tags History and Europe for finding books on European history.
