Possible?

for example: when I click behind my character the character runs backwards

for example: left click moves the character instead of HOLDING left+right click



why am I trying to do this?: because i prefer that my right hand is completely in control of the character and i do not have to use WASD keys to make quick movements such as dodging backwards, flipping 180 degrees, etc.

I understand that not every movement command will be available to a mouse, perhaps unless i have a macro mouse, which I plan to get, but I do not think asking for movement with left click is that much to ask.
