I was unable to access the printer at work, and a coworker showed me a fool proof way to find it. 
i was frustrated because i could not print a document, and a co worker showed me a keyboard shortcut to find it everytime.

That had to be relief. So now you won't have to deal with that frustration again.

Yes indeed, it was frustrating!  I didn't have time to mess with it everytime i had to print something.

Those keyboard shortcuts can be lifesavers.
assistant
Yes they can. I have become much more productive as a result.
