Hashtags are a way of tagging posts and images on social media. They are used heavily on Twitter, Instagram and other services. You can search for posts by hashtag, and use them in your own posts. You don't need to do anything special to create a hashtag, just start using it. Sometimes hashtags are used to express an emotion or something more complex to put an ambiguous post into context, or just for humorous effect.
Helpful info for some of us that see "hashtags", but don't really understand the full context....
I wondered what they were. Do you just use the # key, print your message and then hit
enter? Thank you.
John: Right, you just type # and letters. #likethis
How do Type hashtag? On my UK keyboard its symbol follows the primary £ one.
Michael: I believe it is Option+3. I also think the Option key on some UK keyboards is labelled "Alt" -- look for the ⌥ symbol.
