A bit off topic, but look into urxvtc as well.

Solaris is still vi. You can use arrows but you may have problems. I never looked into why that was.

And hjkl is great. You can edit and move without moving your hands. Tough to get used to though. I just visualized hl as left and right arrows (obvious). for up and down, the first thing you're going to do in a file is move down, and like a good little typist, your index finger should be on j, which is the easiest to find, and easiest to manipulate(??). *shrug* That's what worked for me.

Oooh Aaaal
