        }

        See Fly Mode section for details

Fly Mode
--------

    Fly Mode will always force closed-pair jumping instead of inserting. only for ")", "}", "]"
    If jumps in mistake, could use AutoPairsBackInsert(Default Key: <M-b>) to jump back and insert closed pair.
    the most situation maybe want to insert single closed pair in the string, eg ")"

    Default Options:

        let g:AutoPairsFlyMode = 1
        let g:AutoPairsShortcutBackInsert = '<M-b>'

Shortcuts
---------

    System Shortcuts:
        <CR>  : Insert new indented line after return if cursor in blank brackets or quotes.
        <BS>  : Delete brackets in pair
        <M-p> : Toggle Autopairs (g:AutoPairsShortcutToggle)
        <M-e> : Fast Wrap (g:AutoPairsShortcutFastWrap)
        <M-n> : Jump to next closed pair (g:AutoPairsShortcutJump)
        <M-b> : BackInsert

    If <M-p> <M-e> or <M-n> conflict with another keys or want to bind to another keys, add

        let g:AutoPairShortcutToggle = '<another key>'

    to .vimrc, it the key is empty string '', then the shortcut will be disabled.

Options
-------
*   g:AutoPairs

        Default: {'(':')', '[':']', '{':'}',"'":"'",'"':'"', '`':'`'}

*   g:AutoPairsShortcutToggle

        Default: '<M-p>'

        The shortcut to toggle autopairs.

*   g:AutoPairsShortcutFastWrap

        Default: '<M-e>'

        Fast wrap the word. all pairs will be consider as a block (include <>).
        (|)'hello' after fast wrap at |, the word will be ('hello')
        (|)<hello> after fast wrap at |, the word will be (<hello>)

*   g:AutoPairsShortcutJump

        Default: '<M-n>'

        Jump to the next closed pair

*   g:AutoPairsMapBS

        Default : 1

        Map <BS> to delete brackets, quotes in pair
        execute 'inoremap <buffer> <silent> <BS> <C-R>=AutoPairsDelete()<CR>'

*   g:AutoPairsMapCR

        Default : 1

        Map <CR> to insert a new indented line if cursor in (|), {|} [|], '|', "|"
        execute 'inoremap <buffer> <silent> <CR> <C-R>=AutoPairsReturn()<CR>'

*   g:AutoPairsCenterLine

        Default : 1

        When g:AutoPairsMapCR is on, center current line after return if the line is at the bottom 1/3 of the window.

*   g:AutoPairsMapSpace

        Default : 1

        Map <space> to insert a space after the opening character and before the closing one.
        execute 'inoremap <buffer> <silent> <CR> <C-R>=AutoPairsSpace()<CR>'

*   g:AutoPairsFlyMode

        Default : 1

        see FlyMode section for details.

*   g:AutoPairsShortcutBackInsert

        Default : <M-b>

        Work with FlyMode, insert the key at the Fly Mode jumped postion

TroubleShooting
---------------
    The script will remap keys ([{'"}]) <BS>,
    If auto pairs cannot work, use :imap ( to check if the map is corrected.
    The correct map should be <C-R>=AutoPairsInsert("\(")<CR>
    Or the plugin conflict with some other plugins.
    use command :call AutoPairsInit() to remap the keys.


* How to insert parens purely

    There are 3 ways

    1. use Ctrl-V ) to insert paren without trigger the plugin.

    2. use Alt-P to turn off the plugin.

    3. use DEL or <C-O>x to delete the character insert by plugin.
