" @section edit, layers-edit
" @parentsection layers
" The `edit` layer provides basic feature for editing files.
" This layer is loaded by default. To disable this layer:
" >
"   [[layers]]
"     name = 'edit'
"     enable = false
" <
" @subsection Configuration
" 1. `autosave_timeout`: set the timeoutlen of autosave plugin. By default it
" is 0. And autosave is disabled. timeoutlen must be given in millisecods and
" can't be > 100*60*1000 (100 minutes) or < 1000 (1 second). For example,
" setup timer with 5 minutes:
" >
"   [[layers]]
"     name = 'edit'
"     autosave_timeout = 300000
" <
" 2. `autosave_events`: set the events on which autosave will perform a save.
" This option is an empty list by default. you can trigger saving based
" on vim's events, for example:
" >
"   [[layers]]
"     name = 'edit'
"     autosave_events = ['InsertLeave', 'TextChanged']
" <
" 3. `autosave_all_buffers`: By default autosave plugin only save current buffer.
" If you want to save all buffers automatically. Set this option to `true`.
" >
"   [[layers]]
"     name = 'edit'
"     autosave_all_buffers = true
" <
" 4. `autosave_location`: set the directory where to save changed files. By
" default it is empty string, that means saving to the original file. If this
" option is not an empty string. files will me saved to that directory
" automatically. and the format is:
" >
"   autosave_location/path+=to+=filename.ext.backup
" <
" 5. `enable_hop`: by default, spacevim use easymotion plugin. and if you are
" using neovim 0.6.0 or above, hop.nvim will be enabled. You can disabled this
" plugin and still using easymotion.
"
" @subsection key bindings
"
" The `edit` layer also provides many key bindings:
" >
"   key binding       description
"   SPC x c           count in the selection region
" <
"
" The following key binding is to jump to targets. The default plugin is
" `easymotion`, and if you are using neovim 0.6.0 or above. The `hop.nvim` will
" be used.
" >
"   key binding       description
"   SPC j j           jump or select a character
"   SPC j J           jump to suite of two characters
"   SPC j l           jump or select to a line
"   SPC j w           jump to a word
"   SPC j u           jump to a url
