The KWS becomes a lot more convenient if you make it automatic. There are several ways to do that, but the simplest is to bind the secondary fire button to the "-" key at the extreme top right of your keyboard. Put the KWS on the secondary fire button and all weapons on the primary one. Use fire groups if you want different weapons active at a time. When you arrive at the RES, put a weight on the "-" key. Thereafter, the KWS will automatically scan any ship that you target and shoot without you having to wait. There isn't really any point in getting a KWS better than C- grade when you use this method. If you have an X52 or similar, you can bind the secondary fire button to the slider or a rotational , which both stay on. Obviously, when you leave the RES, you have to remove the weight or switch off because you can't undeploy your weapons with it active. Note that if you have a head tracker, every time you look at the comma panel, the minus key will type a row of minuses and when you look back, you'll have to reset your weight to reactivate the KWS.
