agreed..
being that I have not workd in any CAD type software previously..
this was my first exposure to it..
until I read/learned those two tips.. I found myself struggling a bit..
after.. I went back to Eagle.. and tried to left,right and center click on everything.. at different times.. to see what options or different sub menus I got.
It would be nice to have a small, simple & direct TIP thread for us Eagle users.. 
my next suggestion is to learn how to make your own custom parts.. make your own libraries (where you save/create most of your used components.. or ones you have edited/altered)
also learn how to take an existing schematic and create a library from it.. (great for when you cant find that part/components yourself..butsomeone has it in their current project/schematics/.brd file..etc.
