There are a number of special places in the game where you perform actions
using menus and prompts rather than the normal command and parameter
style interaction. These are:

1. Banks
2. Guilds
3. Guild Stores
4. Mercantiles

To perform bank, treasury or shop transactions, go to one of the special 
rooms (of one of the types specified above) and type "menu" (or just "m" for 
short) to bring up the operations menu for that particular location. Then, 
just follow the menus and prompts to do whatever it is you want to do.

For mercantiles, you can bypass the menu by typing "menu" and then a set of 
parameters. The four options available in a mercantile are Buy (B), Sell (S),
Inventory (I) and Catalog (C). To skip the menu, you can enter these as
parameters along with the "menu" command. For example:

"menu c"       - lists the catalog of items for sale (same as typing "items")
"menu i"       - lists your inventory (same as typing "inventory")
"menu b"       - buy an item
"menu b x"     - buy item #x
"menu s"       - sell an item (or items)
"menu s x y z" - sell items x, y & z

You may find it helpful to set up macros for buying and selling. For example,
you could set macro "sell" to "menu s" and macro "buy" to "menu b". Then
you just type "sell x y z" to sell items from your inventory and "buy x"
to buy items from the mercantile.
