Killing & Yanking

'alt-backspace': 'atomic-emacs:backward-kill-word'
'alt-delete': 'atomic-emacs:backward-kill-word'
'alt-d': 'atomic-emacs:kill-word'
'ctrl-k': 'atomic-emacs:kill-line'

'ctrl-y': 'atomic-emacs:yank'
'alt-y': 'atomic-emacs:yank-pop'
'alt-shift-y': 'atomic-emacs:yank-shift'

Note that Atomic Emacs does not (yet) support prefix arguments, so to rotate the kill ring forward, use yank-shift (equivalent to yank-pop in Emacs with a prefix argument of -1).

Other Packages

For a more Emacs-like version of find-file, install advanced-open-file. Atomic Emacs will use that package if it exists by default instead of Atom's fuzzy-finder. This may be disabled in settings, but note that fuzzy-finder cannot create new files.

Extending Atomic Emacs

Atomic Emacs exposes its core classes via a consumable service. For example, here's how you could extend it to add subword navigation:


atom.workspace.packageManager.serviceHub.consume "atomic-emacs", "^0.13.0", (service) ->
  window.emacs = service

forwardSubword = (event) ->
  emacsEditor = emacs.getEditor(event)
  emacsEditor.moveEmacsCursors (emacsCursor) ->

backwardSubword = (event) ->
  emacsEditor = emacs.getEditor(event)
  emacsEditor.moveEmacsCursors (emacsCursor) ->

atom.commands.add 'atom-text-editor', 'me:forward-subword', (event) -> forwardSubword(event)
atom.commands.add 'atom-text-editor', 'me:backward-subword', (event) -> backwardSubword(event)


  'ctrl-left': 'me:backward-subword'
  'ctrl-right': 'me:forward-subword'

If you're writing an extension package, consume the service as described in the Atom Flight Manual.

Documentation for the Atomic Emacs core classes is sparse, but a common starting point is to get the EmacsEditor for the event as above. The EmacsEditor and EmacsCursor classes in the Atomic Emacs source should be fairly easy to follow.

Something missing?

Windows Note

Some common Emacs keystrokes conflict with the default key bindings on Atom for Windows in unexpected ways. For example, ctrl-k (kill-line on emacs) is a prefix key for a set of pane management commands in Atom for Windows. The result is that after pressing ctrl-k, Atom will wait for 2 seconds to determine if it should treat this as a full command, or the beginning of another command, making kill-line feel "slow".

You can of course disable this by disabling the all built-in key bindings that start with ctrl-k in your keymaps.config file. You can also do this a little easier with the disable-keybindings package.
