Buffers and Sessions

Buffers#

:ls              " what is open
:b <fragment>    " jump to it
:bd              " close one

Sessions#

A session records your open buffers, window layout, and working directory:

:mksession! ~/.config/nvim/sessions/projectx.vim

Restore it later:

nvim -S ~/.config/nvim/sessions/projectx.vim

You come back to the same splits, the same files, the same place — instead of rebuilding your layout every morning.
