This tooltip appears if you hover indecisively over the Save button for a spell. I understand what the message is trying to say, but it still isn’t very clear.
The difference between “click” and “press” is subtle at best, and I believe it would be better to differentiate between the two actions by calling them “click” and “click and hold.” It’s more verbose and linguistically sloppy, but it results in a clearer message.
