/*
    Rather than prompting for each individual item, I think it should be
like multi-pickup, in that pressing a letter only "selects" an item
(changing the '-' next to its name to a '+').
New, suggested shopping keys:
* letter keys [a-t] (de)select item
* Enter buys (with prompt)
* ? toggles examination mode (where letter keys view items)
* \ shows discovered items
* * lists inventory
* x exits (also Esc)
For the ? key, the text should read:
[?] switch to examination mode
[?] switch to selection mode
Display selected items in yellow.
Use red/green letters to indicated availability as now. Update these as
items are (de)selected.
List funds: "You now have 119 gold pieces. After the purchase, you will
have 24 gold pieces."
