A bunch of nifty ways to use the /giphy command in Slack. By far my most used one is the ability to add a custom caption and search for GIFs using a separate phrase. This can be achieved with the following format:
/giphy #caption “quote” <insert phrase here>
For example, you could type
/giphy #caption "Propane and propane accessories." king of the hill to get a nifty King of the Hill GIF with the quoted caption added.
