-Emulated Vim Plugins
---------------------
-
-IdeaVim extensions emulate plugins of the original Vim. In order to use
-IdeaVim extensions, you have to enable them via this command in your `~/.ideavimrc`:
-
-```
-set <extension-name>
-```
-
-If you reuse your existing `.vimrc` file using `source ~/.vimrc`, IdeaVim can parse and enable plugins that are defined
-using [vim-plug](https://github.com/junegunn/vim-plug) or [vundle](https://github.com/VundleVim/Vundle.vim).
-No additional set commands in `~/.ideavimrc` are required.  
-If you'd like to disable some plugin that's enabled in `.vimrc`, you can use `set no<extension-name>`
-in `~/.ideavimrc`.
-
-Available extensions:

-                 This option has effect if you are in normal, insert or replace mode before refactoring start.
-                 Visual or select mode are not changed.
-    
-    
-    `ideajoin`      `ideajoin` Boolean (default false)
-    
-                  If true, join command will be performed via IDE
-                  See wiki/`ideajoin` examples
-                  
-    `ideastatusicon`  `ideastatusicon` String(default "enabled")
-    
-                 Define the behavior of IdeaVim icon in the status bar.
-                 
-                 Use one of the following values:
-                 - enabled - icon is shown in the status bar
-                 - gray - use the gray version of the icon
-                 - disabled - hide the icon
-
-    `ideawrite`     `ideawrite` String (default "all")
-                  "file" or "all". Defines the behaviour of ":w" command.
-                  Value "all" enables execution of ":wa" (save all) command on ":w" (save).
-                  This feature exists because some IJ options like "Prettier on save" or "ESlint on save"
-                       work only with "save all" action. If this option is set to "all", these actions work
-                       also with ":w" command.
-                  
-    `lookupkeys`    `lookupkeys`   List of strings
-    
-                  List of keys that should be processed by the IDE during the active lookup (autocompletion).
-                  For example, <Tab> and <Enter> are used by the IDE to finish the lookup,
-                        but <C-W> should be passed to IdeaVim.
-                  Default value: 
-                        "<Tab>", "<Down>", "<Up>", "<Enter>", "<Left>", "<Right>",
-                        "<C-Down>", "<C-Up>", "<PageUp>", "<PageDown>",
-                        "<C-J>", "<C-Q>"
-                     
-    `ideavimsupport`  `ideavimsupport`  List of strings (default "dialog")
-                  
-                  Define the list of additional buffers where IdeaVim is enabled.
-                  
-                  - dialog - enable IdeaVim in dialogs
-                  - singleline - enable IdeaVim in single line editors (not suggested)
