I used to use the scrollwheel on the mouse to do selections, but I always came up with the same problem - I'd go too fast, select the wrong item. Or I'd go to pull out the medpack and an enemy would come around the corner, leaving me in limbo. However, I had always used the scrollwheel for selections, so I had to force myself from using it.
Remove the key setting for scrolling weapons. This will force you to use the number buttons. Unfortuantely this also disables zooming on the sniper scope and rifle rockets, but it doesn't take long to get into habit, in which case you can put it back. When the option to scroll through weapons is there, you will use it, so this will force you to learn the number buttons and get used to using them in frantic situations.
Its really worth using the number buttons (or special setup, such as mouse buttons) for selecting weapons, the menu is really not efficient enough.
