Get emmet-atom working fine with Atom and autocomplete-plus

keymap.cson

# Will make autocomplete trigger with 'enter' instead of 'tab'
'atom-text-editor:not(mini) .autocomplete-plus.autocomplete-suggestion-list':
  'tab': 'unset!'
  'enter': 'autocomplete-plus:confirm'

# Use 'expand-abbreviation' instead of 'expand-abbreviation-with-tab' for tab keybinding
'.pane .editor:not(.mini)':
  'tab': 'emmet:expand-abbreviation'

So, I tried this and it actually disables the tab key altogether unless there's an abbreviation to be had...

It works great! Thank you for this solution.
