Re-activate all fonts?

[shape+letter]

Hello. 

Not sure if this is correct but I was testing some typekit css name declarations which weren't working properly on a website, so I used the deactivate all fonts button. Now I can't find a way to re-activate all fonts, and from some googling it looks like I may need to run through every single typeface on my plan and manually click to re-activate? 

Surely there's re-activate all button somewhere?

I would think you need to reactivate one by one. I don't imagine it keeps a list of all the fonts you previously had activated.
