This system addresses the "have to cycle through all your grenades-muzzles-satchels to get to the desired weapon/mode" issue.
Weapons/muzzles can now be selected by custom keys, while the 'F' key is limited to switching modes for the currently selected weapon (or grenade/satchel types).
Additionally a non-intrusive "safety" mode is implemented.

There are five custom keys which allow you to quickly select one of the five main "weapons":

• Safety
• Rifle/Pistol (whichever is in hands now)
• Underbarrel GL
• Throwable items (grenades etc)
• Placeable items (mines etc)

Once the "weapon" is selected, you can use the 'F' key to cycle through its fire modes (if it's a firearm) or grenade/mine types if it's either Throw or Put weapon.

See "How to" section for information on configuring the system for your taste.
