On Linux   tested in Ununtu KDE   There is the option in the menu  under Edit   Lines   Auto Indent or press Cmd   Shift   p  search for Editor  Auto Indent by entering just  ai   Note  In KDE ctrl-alt-l is already globally set for  lock screen  so better use ctrl-alt-i instead   You can add a key mapping in Atom    Cmd   Shift   p  search for  Settings View  Show Keybindings   click on  your keymap file  Add a section there like this one     atom-text-editor        ctrl-alt-i    editor auto-indent     If the indention is not working  it can be a reason  that the file-ending is not recognized by Atom  Add the support for your language then  for example for  Lua  install the package  language-lua    If a File is not recognized for your language    open the    atom config cson file  by CTRL SHIFT p  type   open config    add edit a customFileTypes section under core for example like the following   core    customFileTypes       source lua            conf             text html php            thtml            You find the languages scope names   source lua    text html php      in the language package settings see here

The accepted answer works  but you have to do a  Select All  first -- every time -- and I m way too lazy for that   And it turns out  it s not super trivial -- I figured I d post this here in an attempt to save like-minded individuals the 30 minutes it takes to track all this down  -- Also note  this approach restores the original selection when it s done  and it happens so fast  you don t even notice the selection was ever changed    1   First  add a custom command to your init script  File- Open Your Init Script  then paste this at the bottom    atom commands add  atom-text-editor    custom reformat   - gt      editor   atom workspace getActiveTextEditor        oldRanges   editor getSelectedBufferRanges        editor selectAll        atom commands dispatch atom views getView editor    editor auto-indent       editor setSelectedBufferRanges oldRanges     2   Bind  custom reformat  to a key  File- Open Your Keymap  then paste this at the bottom     atom-text-editor        ctrl-alt-d    custom reformat    3   Restart Atom  the init coffee script only runs when atom is first launched
