Atom custom keybindings
# ~/.atom/keymap.cson
# Your keymap
#
# Atom keymaps work similarly to style sheets. Just as style sheets use
# selectors to apply styles to elements, Atom keymaps use selectors to associate
# keystrokes with events in specific contexts. Unlike style sheets however,
# each selector can only be declared once.
#
# You can create a new keybinding in this file by typing "key" and then hitting
# tab.
