I've been trying to learn Emacs lately and really like it so far... except for some of the less familiar key bindings (copy/paste and arrow keys for instance). I've read that ErgoEmacs mode modifies some key bindings so that they are more ergonomic and easy to pick up.
What are the pros and cons of using this mode? All I can think of is it can be harder to follow online tutorials and it won't be on all default installs. Anything I'm leaving out?
