League-of-legends – How to attack move click to kite while only targeting champs

There is a hotkey H which is the equivalent of toggling "Stop", which stops your current action. I'm not sure whether this will do what you need in stopping the auto-attack, but it's worth a try. I don't see any other options that could remotely do what you desire, other than getting stunned.

Continually pacing back and forth within range is a preferable course of action once you learn how to do it without getting exhausted. This actually has a few benefits besides just preventing you from attacking - it makes you a harder target, and it also makes it less detectable to be seen creeping closer and closer towards your opponent to make a pot shot. Alternatively, it makes your opponent uneasy since you can easily be in range to take said shot, which makes them less inclined to stay close.

Clarification of the term "click to attack"

There are two key bindings related to attack:

• Attack move - default button A - when you click A cursor changes into target pick. Clicking left mouse button then makes your character either attack the picked target or run to the picked location and attack the first target that appears in your range during the movement. If there are more targets, it picks the closest one.

• Attack move click - default Shift + Right mouse button - it is a shortcut for Attack move

Advantages of using "click to attack"

• When you chase into a brush you start attacking immediately when you see the target
• When you missclick right button when lasthitting then you go in the creeps and get yourself out of position, that can never happen while using Attack move
• When lasthitting, Attack move checks for a target in a slightly larger radius than right click, which makes it easier to pick the target. It also might be an advantage in larger crowds of creeps when you need to select a creep precisely.

Disadvantages

• When using Attack move during chasing and clicking it on the ground, then if a different eligible target appears closer, you immediately start attacking it. Therefore, you obviously lose some time and even if it is miliseconds it may change the outcome of the chase.
