By default, quick delete is right click. But if you know me, you know I very much dislike this idea. So I re-bind this key to "Del" key.
HOWEVER,
- when you hold down the "del" key and move your cursor across buildings to be deleted, nothing actually happens.
- When you bind it to another key (non-system, such as Numpad5), it starts to work again.
As I use mouse with my left hand sometimes, I bound most of the quick-action keys to the numpad.
The OTHER issue arises:
- Currently, the game differentiates between Left Shift and Right Shift, Left and right Alt, Left and Right Ctrl, and Enter and Numpad Enter.
