The problem is the equations are all entirely integrated with a ton of text and I have to be able to change them often and easily, and its a pain to go back and forth between programs.
What programs are you going back and forth between?
And the arrow key issue isn't about inserting them, its about aiming them. Publishing view solved that...
Ok, so why doesn't copy/paste work? Seems like a copied arrow should be pointing in the same direction and be the same size as the original.
