-// To work around it we use an intermediary linkToCommand command. When

-// the last few links in the map should be good enough. Likewise, we could
-// add code to remove a target command from the map after the link is
-// clicked, but assuming most links in hover sheets won't be clicked anyway
-// this code won't change the overall memory use much.
