What is my Tmux Previous Window?

Today I noticed a symbol in the Tmux bar that I had not noticed before, the dash (-) next to frontend:

0:code* 2:api  3:frontend-

In a Tmux session, asterisk (*) is the window in focus. The dash is the previous window, which you can easily return to. From window 0, code, I can return window 1, frontend, using CTRL + bb.
