Junk Yard · Keyboard shortcuts
Why doesn't the Junk Yard shortcut do anything?
Short answer: Make sure the Junk Yard is enabled, the shortcut's own switch is on in Settings → Junk Yard, Storage Studio is running, and no other app uses the same keys.
Check three things. The Junk Yard must be switched on (Settings → Junk Yard → Enable Junk Yard on this Mac); the shortcut's own switch must be on in Settings → Junk Yard; and no other app may be using the same keys.
If another app grabs the combination first, choose a different one for the Junk Yard. Storage Studio itself also needs to be running — the shortcuts work from any app only while it's open in the menu bar.
