If I remember correctly, pressing 5 on the num pad will attack enemies positioned on top of you in CVRL. You can attack and move diagonally the same as enemies can, and you'll generally have better range than them to boot.
I'll try to think of a good beginner's roguelike.
Edit:
Alright, maybe you'll like one of these two. They both have persistent levels and graphics so it's easier to figure out what's going on at first.
Castle of the Winds (the link is near the bottom of the page) was one of the first roguelikes I played. The interface is easy, the difficulty is merciful by roguelike standards, and the game itself isn't bad either.
Ragnarok is another old favorite of mine. You can use the mouse for the interface if you want, and the buttons are clearly labeled. Bear in mind that an easy interface doesn't mean the game itself is easy. Until you learn all the tricks, Ragnarok is brutal. You will probably need to use DOSBox to get it running.
Edit 2:
Have you tried Larn? That one uses ASCII graphics and has persistent levels. It's shorter than CotW and Ragnarok. The difficulty is easier than average for a roguelike, but if you win, it gets harder for the next time.
