A "key ring" that would take up 1 Inventory slot that would hold all of your keys, including Pact Crowbars, Exalted Keys, Vials of Chak Acid, Bandit Skeleton Keys, Machetes, Trader's Keys, Zephyrite Locpicks, Keys of Greater Nightmare, etc. Any key acquired would go to the key ring automatically. The key ring could be put in a Shared Inventory slot and used by all of your toons.Another suggestion would be a "hot inventory" item. Any item placed in this special Inventory slot would show up as a skill to the right of the mount skill on your screen, and could have a hot key assigned to it. If I placed a Stealth Disruptor Trap in this inventory slot, it would show up in the "hot inventory" skill box, and when a @$#$%# Thief disappears in WvW I can click or hot key it to immediately set the trap without having to open my inventory first.
