Getting Started
Welcome to Atom! This guide provides a quick introduction so you can be productive as quickly as possible. There are also guides which cover configuring, theming, and extending Atom.
The Command Palette
If there's one key-command you remember in Atom, it should be cmd-shift-P. You
can always press cmd-shift-P to bring up a list of commands (and key bindings)
that are relevant to the currently focused interface element. This is a great
way to explore the system and learn key bindings interactively. For information
about adding or changing a key binding refer to the customizing key
bindings section.
The Basics
Working With Files
Atom windows are scoped to the directory they're opened from. If you launch Atom from the command line everything will be relative to the current directory. This means that the tree view on the left will only show files contained within that directory.
This can be a useful way to organize multiple projects, as each project will be contained within its own window.
Finding Files
The fastest way to find a file is to use the fuzzy finder. Press cmd-t and
begin typing the name of the file you're looking for. If you are looking for a
file that is already open press cmd-b to bring up a searchable list of open
files.
You can also use the tree view to navigate to a file. To open or move focus to
the tree view, press cmd-\. You can then navigate to a file using the arrow
keys and select it with return.
Adding, Moving, Deleting Files
Currently, all file modification is performed via the tree view. To add a file,
select a directory in the tree view and press a. Then type the name of the
file. Any intermediate directories you type will be created automatically if
needed.
To move or rename a file or directory, select it in the tree view and press m.
To delete a file, select it in the tree view and press delete.
Searching
Find and Replace
To search within a buffer use cmd-f. To search the entire project use
cmd-shift-f.
Navigating By Symbols
If you want to jump to a method press cmd-r. It opens a list of all symbols
in the current file.
To search for symbols across your project use cmd-shift-r, but you'll need to
make sure you have a ctags installed and a tags file generated for your project.
Also, if you're editing CoffeeScript, it's a good idea to update your ~/.ctags
file to understand the language. Here is a good example.
Split Panes
You can split any editor pane horizontally or vertically by using cmd-k right or
cmd-k down. Once you have a split pane, you can move focus between them with
cmd-k cmd-right or cmd-k cmd-down. To close a pane, close all tabs inside it.
Folding
You can fold everything with alt-cmd-{ and unfold everything with
alt-cmd-}. Or, you can fold / unfold by a single level with alt-cmd-[ and
alt-cmd-].
Soft-Wrap
If you want to toggle soft wrap, trigger the command from the command palette.
Press cmd-shift-P to open the palette, then type "wrap" to find the correct
command.
Configuration
Press cmd-, to display the a settings pane. This serves as the primary
interface for adjusting config settings, installing packages and changing
themes.
For more advanced configuration see the customization guide.
