See your bank contents

[Itanius]

/show_window Inventory.Bank

You can use this anywhere to view your bank contents. You can open containers, examine items, and you can even drag items into chat to make links. But, you cannot move items in or out of the bank, since you're not in a Bank Transaction.

This means Quest Items you need to examine to further the progress of a quest can be left in the bank.

Enjoy.
