1. Introduction                         *easymotion* *easymotion-introduction*

EasyMotion provides a much simpler way to use some motions in vim. It takes
the <number> out of <number>w or <number>f{char} by highlighting all possible
choices and allowing you to press one key to jump directly to the target.

When one of the available motions is triggered, all visible text preceding or
following the cursor is faded, and motion targets are highlighted.

==============================================================================
2. Usage                                                    *easymotion-usage*

EasyMotion is triggered by one of the provided mappings (see
|easymotion-default-mappings| for details).

Example: >

    <cursor>Lorem ipsum dolor sit amet.

Type <Leader><Leader>w to trigger the word motion |w|. See
|easymotion-leader-key| for details about the leader key. When the
motion is triggered, the text is updated (no braces are actually added,
the text is highlighted in red by default): >

    <cursor>Lorem {a}psum {b}olor {c}it {d}met.

Press "c" to jump to the beginning of the word "sit": >

    Lorem ipsum dolor <cursor>sit amet.

Similarly, if you're looking for an "o", you can use the |f| motion.
Type <Leader><Leader>fo, and all "o" characters are highlighted: >

    <cursor>L{a}rem ipsum d{b}l{c}r sit amet.

Press "b" to jump to the second "o": >

    Lorem ipsum d<cursor>olor sit amet.

And that's it!

------------------------------------------------------------------------------
2.1 Default mappings                             *easymotion-default-mappings*

The default configuration defines the following mappings in normal,
visual and operator-pending mode:

    Mapping           | Details
    ------------------|----------------------------------------------
    <Leader>f{char}   | Find {char} to the right. See |f|.
    <Leader>F{char}   | Find {char} to the left. See |F|.
    <Leader>t{char}   | Till before the {char} to the right. See |t|.
    <Leader>T{char}   | Till after the {char} to the left. See |T|.
    <Leader>w         | Beginning of word forward. See |w|.
    <Leader>W         | Beginning of WORD forward. See |W|.
    <Leader>b         | Beginning of word backward. See |b|.
    <Leader>B         | Beginning of WORD backward. See |B|.
    <Leader>e         | End of word forward. See |e|.
    <Leader>E         | End of WORD forward. See |E|.
    <Leader>ge        | End of word backward. See |ge|.
    <Leader>gE        | End of WORD backward. See |gE|.
    <Leader>j         | Line downward. See |j|.
    <Leader>k         | Line upward. See |k|.
    <Leader>n         | Jump to latest "/" or "?" forward. See |n|.
    <Leader>N         | Jump to latest "/" or "?" backward. See |N|.

See |easymotion-leader-key| and |mapleader| for details about the leader key.
See |easymotion-custom-mappings| for customizing the default mappings.

==============================================================================
3. Requirements                                      *easymotion-requirements*

EasyMotion has been developed and tested in vim 7.3, but it should run without
any problems in vim 7.2.

Vi-compatible mode must be disabled.

==============================================================================
4. Configuration                                    *easymotion-configuration*

EasyMotion will work fine without any configuration, but you can override the
default behavior by setting configuration variables globally in your |vimrc|
file.

Example (this will change the target keys and disable shading): >

    let g:EasyMotion_keys = '1234567890'
    let g:EasyMotion_do_shade = 0

------------------------------------------------------------------------------
4.1 EasyMotion_keys                                          *EasyMotion_keys*

Set the keys which will be used for motion targets. Add as many keys as you
want. There's a lower chance that the motion targets will be grouped if many
keys are available.

Default: 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'

------------------------------------------------------------------------------
4.2 EasyMotion_do_shade                                  *EasyMotion_do_shade*

The default behavior is to shade the text following the cursor (forward
motions) or preceding the cursor (backward motions) to make the motion targets
more visible. Set this option to 0 if you want to disable text shading.

Default: 1

------------------------------------------------------------------------------
4.3 EasyMotion_do_mapping                              *EasyMotion_do_mapping*

Set this option to 0 if you want to disable the default mappings. See
|easymotion-default-mappings| for details about the default mappings.

Note: If you disable this option, you'll have to map the motions yourself. See
the plugin source code for mapping details. You usually shouldn't need to do
this, see |easymotion-custom-mappings| for customizing the default mappings.

Default: 1

------------------------------------------------------------------------------
4.4 EasyMotion_grouping                                  *EasyMotion_grouping*

When there are too many possible targets on the screen, the results have to be
grouped. This configuration option lets you change which grouping algorithm
you want to use. There are two grouping algorithms available:

    *  Single-key priority (value: 1)
       -------------------

       This algorithm prioritizes single-key jumps for the targets closest to
       the cursor and only groups the last jump targets to maximize the amount
       of single-key jumps.

       This algorithm works recursively and will work with as few keys as two.

       Example (with |EasyMotion_keys| = "abcdef"): >

       x x x x x x x x x
<
       The |w| motion is triggered: >

       a b c d e f f f f
       ^ ^ ^ ^ ^           Direct jump to target
                 ^ ^ ^ ^   Enter group "f"
<
    *  Original (value: 2)
       --------

       This is the original algorithm which always groups all targets if there
       are too many possible motion targets.

       Example (with |EasyMotion_keys| = "abcdef"): >

       x x x x x x x x x
<
       The |w| motion is triggered: >

       a a a a a a b b b
       ^ ^ ^ ^ ^ ^         Enter group "a"
                   ^ ^ ^   Enter group "b"

Default: 1

------------------------------------------------------------------------------
4.5 Custom highlighting                                 *easymotion-custom-hl*

The default EasyMotion configuration uses two highlighting groups that link
to groups with default values. The highlighting groups are:

    * EasyMotionTarget

      Highlights motion targets, the default value is bold red

    * EasyMotionShade

      Highlights shaded text, the default value is dark gray

There are two ways to override the default colors:

   1) Set the highlighting in your color scheme

      This will only affect a single color scheme. The default red/gray colors
      will be used if you change the color scheme to one that doesn't assign
      any EasyMotion colors.

      Example: >

          hi EasyMotionTarget ctermbg=none ctermfg=green
          hi EasyMotionShade  ctermbg=none ctermfg=blue
<
   2) Set the highlighting in your vimrc

      This is ideal if you want to link the colors to highlighting groups that
      are available in almost every color scheme, e.g. |ErrorMsg| (usually
      bright red) and Comment (usually faded). You can be sure that the
      color scheme's colors will be used instead of the default red/gray
      if you choose this option.

      Example: >

          hi link EasyMotionTarget ErrorMsg
          hi link EasyMotionShade  Comment
<
------------------------------------------------------------------------------
4.6 Custom mappings                               *easymotion-custom-mappings*

EasyMotion allows you to customize all default mappings to avoid conflicts
with existing mappings. It is possible to change the default leader key
of all mappings to another key or sequence. It is also possible to fine
tune the plugin to your need by changing every single sequence.

4.6.1 Leader key               *EasyMotion_leader_key* *easymotion-leader-key*

The default leader key can be changed with the configuration option
|EasyMotion_leader_key|.

Set this option to the key sequence to use as the prefix of the mappings
described in |easymotion-default-mappings|.

Note: The default leader key has been changed to '<Leader><Leader>' to 
avoid conflicts with other plugins. You can revert to the original 
leader by setting this option in your vimrc: >

    let g:EasyMotion_leader_key = '<Leader>'
<
Default: '<Leader><Leader>'

4.6.2 Custom Keys                                     *easymotion-custom-keys*

All custom mappings follow the same variable format: >

    EasyMotion_mapping_{motion} = {mapping}
<
Example: >

    let g:EasyMotion_mapping_f = '_f'
    let g:EasyMotion_mapping_T = '<C-T>'
<
See |easymotion-default-mappings| for a table of motions that can be mapped
and their default values.

Note: The leader key defined by |EasyMotion_leader_key| is not prepended to
your customized mappings! You have to provide full key sequences when setting
these options.
