Wow I just now understood why knowing your Key commands are very important especially for pro tool users. It is the short cut for pro tools and will save you a ton of time in your session. I strongly advise everyone out there to know their basic command to the tip opf their finger including myself.
I was in a studio last night recording and saw how the engineer was moving around stuff from importing Audio till the session was over with mostly using key commands. of course as an artist and as a audio engineer student I was motivated and payed close attention. In all I could see some confidence in the engineer and that made me be confident and trust what he is doing.
