Hi,
I know to use the arrow keys to move around in a 3D world and to use the mouse vertical motion to lookup/down. What other keys are used in most games for standard motion?

Shooting I suppose is done with Space button. How about picking up items or 'ducking' to avoid being hit or even jumping?

I am working a game concept and need to setup a standard set of keys.

I am not a great game player so my experience is fairly limited to cursors and spacebars.

Regards,
ChuckB
