Press Select, or 'End' and you can switch from the move names to the move inputs.
To be honest, i think the ability to do that/those combos has nothing to do with the keyboard. Generally, using the keyboard is a lot more difficult and your fingers need to be more dextrous, but there isn't much that stick users can do, that keyboard users can't do at all (360/720s?)
I just tried the Balrog Hard 1 on keyboard, and it's exactly the same as for a stick.
Charge FA to lvl 3, once he starts to attack, let go, and double tap forward.
Immediately hold down afterwards.
Then with very deliberate actions, press MK, then LK. (press each button ONCE only)
If LK doesn't come out, repeat again, but wait longer after MK.
If LK comes out, but doesn't combo properly, repeat again, and wait less time after MK.
Once you have the timing right, perform the combo up to LK, after you release LK, do the headbutt - release down and immediately press up, while pressing any punch (you can spam punch if you want)
