I do it all the time
i look for a shortcut, if it will save me time.
and it works for me.
ps like now i have one coming up.
Just found out command:pdfattach will not import to my default layer of preference
So, i added this to LM:layerdirector to get that right for the rest of my AutoCAD drawing life.
Will save a bunch of clicking with pdf's. I see it as (more) nice keystrokes to save time dureing production.
