Add Command To Move/Select To First Letter

• Add the command in init.coffee

atom.commands.add 'atom-text-editor', 'custom:move-to-first-letter': ->
    editor = atom.workspace.getActiveTextEditor()
    if !editor
      return 
    cursor = editor.getLastCursor()
    line = editor.lineTextForBufferRow(cursor.getBufferRow())
    match = /[a-zA-Z]/.exec(line)
    if !match 
      return
    cursor.setBufferPosition([cursor.getBufferRow(), match.index])

atom.commands.add 'atom-text-editor', 'custom:select-to-first-letter-of-line': ->
    editor = atom.workspace.getActiveTextEditor()
    if !editor
      return 
    cursor = editor.getLastCursor()
    selections = editor.getSelections()
    line = editor.lineTextForBufferRow(cursor.getBufferRow())
    match = /[a-zA-Z]/.exec(line)
    if !match 
      return
    firstLetterPos = [cursor.getBufferRow(), match.index]
    selections[0].setBufferRange([firstLetterPos, cursor.getBufferPosition()])

• Add the shortcut in keymap.cson

'atom-text-editor':
  'ctrl-cmd-left': 'custom:select-to-first-letter-of-line'
