I just switched from AutoCad Lt 2009 for PC to AutoCad Lt for Mac and having a lot of trouble -

can you get the ribbon format?

when i select more than one item - do i always have to hold the shift key - is there a way to change that?

i like to keep the snaps off and then use them for each line - can i do that ? like start a line from a midpoint and go to a perpendicular point ?

is there a good manual?
