Using #Hashtags

#Hashtags can be used anywhere in Ledger, including chats, to quickly reference something with a quick link. Simply add a hashtag and it will pull up the five most recent items you created or belong to. You can select one from the list or continue typing after the # to refine your search. Once selected, the item will be added to your comment as a link. 

So now you can create a meeting in events and remind everyone in your stream to participate with a seamless link. There are countless possibilities.
