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:AutoPairs_FlyMode = 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.

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 x to delete the character insert by plugin.
