atom keymap to fix some emmet problems

keymap.cson

# Your keymap
#
# Atom keymaps work similarly to stylesheets. Just as stylesheets use selectors
# to apply styles to elements, Atom keymaps use selectors to associate
# keystrokes with events in specific contexts.
#
# You can create a new keybinding in this file by typing "key" and then hitting
# tab.
#
# Here's an example taken from Atom's built-in keymap:
#
# '.editor':
#   'enter': 'editor:newline'
#
# '.workspace':
#   'ctrl-P': 'core:move-up'
#   'ctrl-p': 'core:move-down'
#
'body':
  'ctrl-alt-cmd-r': 'window:reload'

# '.editor:not(.mini)':
#   'shift-tab': 'emmet:expand-abbreviation'
#

# 'atom-text-editor[data-grammar="text html php"]:not([mini])':
#     'tab': 'emmet:expand-abbreviation-with-tab'

'atom-text-editor:not([mini])':
  'ctrl-e': 'unset!'
  'ctrl-e': 'editor:move-to-end-of-line'

'.platform-darwin atom-pane atom-text-editor:not([mini])':
  'cmd-/': 'editor:toggle-line-comments'
