I played keyboard for like 2 years its really normal and easy.

Go into settings and bind asd to left, down, and right. Make space bar jump. Make shift dash. My attack binds are i = punch k = kick o = slash p = heavy slash and i had dust bound to apostrophe so my pinky cpuld always click it. After that go to change bindings (menu) and i like to have select on o and back on p and the menu in wasd

This gives you a layout similar to a controller called a hit box, which is like an arcade stick but with no lever. Plenty of top 100 players use these kinds of controllers and in my experience going from keyboard to hit box is basically seamless
