    'prefix': 'sl'
    'body': '<!-- silde -->'

'.source.md':
  'new vertical slide':
    'prefix': 'slv'
    'body': '<!-- slide vertical=true-->'

The manual says not to use the same key twice.

'.source.md':
  'new slide':
    'prefix': 'sl'
    'body': '<!-- silde -->'
  'new vertical slide':
    'prefix': 'slv'
    'body': '<!-- slide vertical=true-->'
