First if you haven’t yet heard about vim-airline plugin, and you’re a Vim user, you really owe it to yourself to check it out.
By default vim-airline displays the opening buffers on the top part of the window.
So how to navigate between those buffers? Well, according to this, it seems those buffers are for visual only. To navigate between them, we can use
:bp for previous buffer, and
:bn for next buffer. Alternatively, we can use
:ls to list all buffers, then navigate to a particular buffer by running
:number (substitute number with an actual number).
However, if you know any better or more elegant ways to switch between the opening buffers, please do share!
