Atom Editor

Basic Terminology

Buffer

A buffer is the text content of a file in Atom. It’s basically the same as a file for most descriptions, but it’s the
version Atom has in memory. For instance, you can change the test of a buffer and it isn’t written to its associated
file until you save it.

Pane

A pane is a visual section of Atom. If you look at the welcome screen we just launched, you can see four Panes -
the tab bar, the gutter (which has line numbers in it), the status bar at the bottom and finally the text editor.

Command Palette

In that welcome screen, we are introduced to probably the most important command in Atom, the “Command Palette”.
