Use the binding named Open All Bags if you want your reagent bag to open with the rest of your inventory in WoW Forever. Do not assume the key that opens your backpack triggers the same action, even when your ordinary bags are combined.

This guide is checked against the interface source for beta build 1.60.1.70532. It covers opening controls, not a tested list of every bag or item the reagent slot accepts.

Bind Open All Bags

Open your keybinding settings and find Open All Bags. Assign the key you want to use, check whether it replaces another action, and save the change.

With a reagent bag equipped, test that binding rather than your old backpack shortcut. The important part is selecting the all-bags action, not copying B or Shift+B from another player's setup. Your profile may use different keys.

Why combined bags can still leave you confused

The checked Forever interface defines separate commands for the backpack, the reagent bag and all bags. Its all-bags path includes reagent-bag frames. The backpack command is a different action.

A combined view does not make those bindings identical. If you have been using the backpack action, selecting Open All Bags is the first control to check before replacing bags or changing addons.

The same distinction appeared in an October beta player report: combined bags made the existing backpack shortcut look like the all-bags command, but the player confirmed the separate binding was the missing step.

Opening a bag does not change what fits

If a bag will not equip, or an item will not go inside it, that is a separate compatibility question. The opening command does not override storage restrictions.

Gamepad mode also has separate handling in the interface code. Use its displayed controls rather than assuming a keyboard shortcut applies.

If the all-bags action still behaves differently, keep the exact build, binding name, input mode and combined-bag setting with your report. An old beta complaint alone is not proof that the same bug exists in your current build.
