For those looking to replicate how most isometric ARPG’s work with regards to force stand still/attack in place (shift key by default for both left/right mouse button), the new UI addition allows for that in the current 40.1.1.19 patch that was also rolled out for open beta.

Only the right/left mouse click for movement needs to be checked off for the behavior to work. The other two advanced options are personal preferences for players who prefer skills/actions to work based on the direction their character is facing as opposed to where the mouse pointer is located – best to try each out and notice their subtle differences.
Likewise, something similar to force move can be accomplished by completing unbinding movement from both left and right click, changing the keybinding for stand in place from left-shift to space bar, and holding that down while left/right click mousing around (you then let off the space bar to fire off your left/right button skills).
