" Vim is based on Vi. Setting `nocompatible` switches from the default
" Vi-compatibility mode and enables useful Vim functionality. This
" configuration option turns out not to be necessary for the file named
" '~/.vimrc', because Vim automatically enters nocompatible mode if that file
" is present. But we're including it here just in case this config file is
" loaded some other way (e.g. saved as `foo`, and then Vim started with
" `vim -u foo`).

" This enables relative line numbering mode. With both number and
" relativenumber enabled, the current line shows the true line number, while
" all other lines (above and below) are numbered relative to the current line.
" This is useful because you can tell, at a glance, what count is needed to
" jump up or down to a particular line, by {count}k to go up or {count}j to go
" down.

" The backspace key has slightly unintuitive behavior by default. For example,

" By default, Vim doesn't let you hide a buffer (i.e. have a buffer that isn't
" shown in any window) that has unsaved changes. This is to prevent you from "

" hidden buffers helpful enough to disable this protection. See `:help hidden`
