What do the symbols mean after running :ls in Vim?

vim

Solution

See `:help :ls`.

The hash sign marks the alternate buffer. This is useful for switching between two buffers: it's the buffer that you'll switch to when using e.g. `:b#`. This is the only thing resembling most recently used that you'll get with vim buffers, without plugins.

You also know from `:ls` which buffers have unsaved modifications: `+`.

Problem

After running the list buffers command (`:ls`) in Vim, what do the symbols displayed before some buffers mean? I know the percent sign (`%`) indicates the currently visible buffer. However, I also see the hash sign (`#`), and I can't figure out what that means. Googling this has proved fruitless.
