Comment LaTeX + AucTeX outght to do it (Score 1) 823
I don't see the problem; it seems like you should be able to easily beat the Prof. at writing equations with a (good) text editor you know well and LaTeX.
With the AUCTeX mode for Emacs, you get lots of shortcuts (like 'electric' backslashes and quick commands for environments) plus in-buffer previews.
Add in judicious copy+paste and you should be able to run circles around most professors writing on a blackboard and have plenty of time to read slashdot comments. If they are using an overhead or powerpoint, it might be a little trickier, but hopefully they are handing out notes.
