I learned something new about my Mac tonight. While I was reading an article online, I wanted a quick way to look up the meaning of “fiat.” I knew that in Safari, if you highlight a word and right-click, an option in the resulting menu allows you to look that work up in the native dictionary app:
Also, with a highlighted word in Safari, you can choose Safari > Services> Look Up in Dictionary:
But I’m using Firefox, and in Firefox, neither of these options are available. I learned by experimenting, though, that I could highlight a word and then drag it to the dictionary app icon in my dock. The dictionary opens up and reveals the definition of my word. I love finding little usability gems. Put this one on the list.
