push control 1 to just attack someone with your sword.
Quite litteraly.

Left Ctrl switch your left mouse button from mark to destroy.

And yes, we are moving quite often ... usualy when on line of sight there is another enemy, or something similar.
It would be nice if Larian somehow implement warning for us that our character will need to move to attack this creature ... since in wider spaces, you usualy dont see your character ... and therefore you dont see the shadow/ghost figure that is showing where will you move. :-/
There are also AoO indicators, small red arrows under our enemy feets ... but they are often covered by enviroment, or invisible in blood.

Sadly, in this particular patch bug occured that is showing the path of projectile incorectly ... so even if you wish to throw (or cast) something and trajectory seem to be reaching your target, sometimes it stuck to some object on the way instead.

Especialy frustrating with throwing stuff ...
