What does the :ls command do in VIM Adventures?

Question

I don't understand the output of :ls (note no exclamation point) in VIM Adventures. Here's what it says for me:

1   %   ground

Anyone know what that means?

Answer 1

According to the Vim Wiki:

To list all buffers use the :ls command. Each buffer is assigned a number that is displayed in the first column.

The second column describes the state of the buffer. The different states are explained at :help :ls. The third column is the file name associated with the buffer.

So the first column is just a number for what buffer it is. Looking at the :help :ls page, % means the buffer is the current window. Lastly, ground simply means the name of the file that is associated with the buffer.

Answer 2

Starting with level 11, you have to be able to switch between the buffers. One is named "ground", which is the only one you can see (with the :ls command) before level 11.
