How to change Atom Keybindings

You have to go to Edit -> Preferences -> Keybinding. In this tab you can see your actual binding and if you want to change it, you can access to the keymap file and overcharged configuration.

To access this file you can click on the link below the "Keybindings" title.

For example, if you want to replace the CtrlShiftK by CtrlShiftY, search it in the list, click on the copy icon to copy the configuration line, and put the line into the keymap file and replace the shortcut.

For this example the new line is

'atom-text-editor:not([mini])':
  'ctrl-shift-Y': 'editor:delete-line'

This line replace ctrl-shift-K by ctrl-shift-Y. You have to relaunch Atom to apply this change.

To override existing atom keybindings, just paste the new keybinding in

~/.atom/keymap.cson

If you want emacs keybindings for atom, get all the keybindings from, https://github.com/dvorka/atom-editor-emacs-key-bindings/blob/master/keymap.cson

TO APPLY:

$ gedit ~/.atom/keymap.cson

gedit is the editor available in gnome, you can also use vi or emacs or even nano to edit.

$ vi ~/.atom/keymap.cson

$ emacs -nw ~/.atom/keymap.cson

$ nano ~/.atom/keymap.cson

modify, save & exit. Restart atom, Done!
