I've posted on this in the past.  Any modifier keys are bad, because
they strain the hand in unnatural ways.  There are several medical
problems that can come from overuse of the wrong fingers, especially
using the pinky finger (which is weakest) to hit key combinations.
I'm a heavy Emacs user, and I map as much as possible to single-key
combinations (Meta is just "Escape" for me, I usually don't use Alt).
If I have to use modifiers, I make sure I use either the thumb (the
strongest finger) or multiple fingers at once.

I had wrist and finger joint problems before adopting the "no
modifiers when possible" rule, and have been OK since.  I would
recommend it to anyone concerned about their physical health who types
more than 2 hours per day.  Of course, you should also consult an
ergonomics specialist or a doctor if you are uncomfortable or in pain,
and consider things like elbow angle, eye level with the top of the
monitor, etc.  This is just my experience, and I hope others find it
useful.

For Ion specifically, I've long used the keypad.  It's almost never
used by applications, so why not?  Here's a summary without the actual
config stanza, just the interesting bits.  Just think about how often
you use the keypad--almost never!  Try this for a few days and you'll
see how convenient keypad-based navigation is.
