-- Vi (not Vim) is a POSIX standard, and [has a spec](https://pubs.opengroup.org/onlinepubs/9699919799/utilities/vi.html)! Vim is mostly POSIX compliant when Vi compatibility is selected with the `'compatible'` option, but there are still some differences that can be changed with `'copoptions'`. The spec is interesting because it documents the behaviour of different commands in a stricter style than the user documentation, describing the current line and column after the command, for example. [More details can be found by reading `:help posix`](https://vimhelp.org/vi_diff.txt.html#posix).

-When IdeaVim is hosted in an IntelliJ-based IDE (but not JetBrains Fleet), the following options map to the equivalent IDE settings:
+    `ideamarks`      `ideamarks` Boolean (default true)
+    
+                     If true, creation of global mark will trigger creation of IDE's bookmark
+                     and vice versa.
+                     
+    `idearefactormode` `idearefactormode` String(default "select")
+    
+                 Define the mode that would be enabled during
+                 the refactoring (renaming, live template, introduce variable, etc)
+                 
+                 Use one of the following values:
+                 - keep  - keep the mode that was enabled before starting a refactoring
+                 - select - start refactoring in select mode
+                 - visual - start refactoring in visual mode
+                 
+                 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)

+    `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

+                  "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

+    
+                  List of keys that should be processed by the IDE during the active lookup (autocompletion).

+                        but <C-W> should be passed to IdeaVim.
+                  Default value:

-## IdeaVim options for IntelliJ-based IDE features
-
-Some Vim features cannot be implemented by IdeaVim, and must be implemented by the host IDE, such as showing whitespace and line numbers, and enabling soft-wrap.
-The following options modify equivalent settings and features implemented by IntelliJ-based IDEs.
-
-There is some mismatch when trying to map Vim options, most of which are local options, to IDE settings, which are mostly global-local.
-The Vim option will always reflect the effective value of the IDE setting for the current editor, and modifying the Vim option will update the local value of the IDE setting.
-The default value of the Vim option set during startup is not passed to the IDE setting.
-
-If the IDE setting has a way to modify the local value, such as entries in the _View | Active Editor_ menu, then changing this will update the current editor and be reflected in the Vim option value.
-If the IDE setting can only modify its global setting in the main _Settings_ dialog, this change does not always update the current editor (because the local IDE setting has been modified and takes precedence).
-
-IdeaVim tries to make this work more naturally by updating the editor and local Vim option when a global value changes unless the Vim option has been explicitly set in Command-line mode.
-
-In other words, if the local Vim value is explicitly set for a window or buffer, interactively, then it should not be reset.
-If the Vim option was explicitly set in `~/.ideavimrc` however, then the value will be reset, because this can be viewed as a "global" value - set once and applied to subsequently opened windows.
-(This should not be confused with Vim's concept of global options, which are mainly used to initialise new windows.)
-
-The local Vim option can always be reset to the global IDE setting value by resetting the Vim option to default with the `:set {option}&` syntax.

-'bomb'              'bomb'  Add or remove a byte order mark (BOM) to the
-                            current file. Unlike Vim, the file is modified
-                            immediately, and not when saved

-'cursorline'        'cul'   Highlight the line containing the cursor
-'fileencoding'      'fenc'  Change the encoding of the current file. The file
-                            is modified and written immediately, rather than
-                            waiting to be saved
-                            Note that the names of the encoding might not
-                            match Vim's known names
-'fileformat'        'ff'    Change the file format - dos, unix or mac
-                            The file is modified immediately, rather than
-                            when saved

-## IdeaVim only options
-
-These options are IdeaVim only, and not supported by Vim.
-They control integration with the host IDE.
-Unless otherwise stated, these options do not have abbreviations.
-
-```
-'ideacopypreprocess'    boolean (default off)
-                        global or local to buffer
-        When enabled, the IDE will run custom copy pre-processors over text
-        copied to registers. These pre-processors can perform transformations
-        on the text, such as converting escape characters in a string literal
-        into the actual control characters in a Java file.
-
-        This is not usually the expected behaviour, so this option's default
-        value is off. The equivalent processing for paste is controlled by the
-        "ideaput" value to the 'clipboard' option.
-
-'ideaglobalmode'        boolean (default off)
-                        global
-        This option will cause IdeaVim to share a single mode across all open
-        windows. In other words, entering Insert mode in one window will
-        enable Insert mode in all windows.
-
-'ideajoin'              boolean (default off)
-                        global or local to buffer
-        When enabled, join commands will be handled by the IDE's "smart join"
-        feature. The IDE can change syntax when joining lines, such as merging
-        string literals or if statements. See the wiki for more examples. Not
-        all languages support smart join functionality.
-
-'ideamarks'             boolean (default on)
-                        global
-        Maps Vim's global marks to IDE bookmarks.
-
-'idearefactormode'      string  (default "select")
-                        global or local to buffer
-        Specifies the mode to be used when a refactoring selects text to be
-        edited (e.g. renaming, live template fields, introduce variable, etc):
-           keep         Keep the current mode
-           select       Switch to Select mode
-           visual       Switch to Visual mode
-
-        This option is only used when the refactoring is started in Normal,
-        Insert or Replace mode. Visual or Select modes are not changed.
-
-'ideastatusicon'        string  (default "enabled")
-                        global
-        This option controls the behaviour and appearance of the IdeaVim icon
-        in the status bar:
-           enabled      Show the icon in the status bar
-           gray         Show the gray version of the icon
-           disabled     Hide the icon
-
-'ideavimsupport'        string  (default "dialog")
-                        global
-        A comma-separated list of additional buffers or locations where
-        IdeaVim should be enabled:
-           dialog       Enable IdeaVim in editors hosted in dialogs
-           singleline   Enable IdeaVim in single line editors (not recommended)
-
-        The IDE's editor component can be used in many places, such as VCS
-        commit tool window, or inside dialogs, and even as single line fields.
-
-'ideawrite'             string  (default "all")
-                        global
-        This option defines the behaviour of the :w command:
-           file         Save the current file only
-           all          The :w command works like :wa and invokes the Save All
-                        IDE action. This allows options such as "Prettier on
-                        save" or "ESlint on save" to work with the :w command,
-                        but means all files are saved.
-
-'lookupkeys'            string  (default "<Tab>,<Down>,<Up>,<Enter>,
-                                          <Left>,<Right>,<C-Down>,<C-Up>,
-                                          <PageUp>,<PageDown>, <C-J>,<C-Q>")
-                        global
-        Comma-separated list of keys that should be processed by the IDE while
-        a code completion lookup popup is active. For example, <Tab> and
-        <Enter> are used by the IDE to complete the lookup and insert text,
-        but <C-W> should be passed IdeaVim to continue editing the text.
-
-'trackactionids'        boolean (default off)
-                        global
-        When on, IdeaVim will try to track the current IDE action and display
-        the action name in a notification. This action ID can then be used in
-        a mapping to the action in the form <Action>(...).
-
-'visualdelay'           number  (default 100)
-                        global
-        This option specifies the delay, in milliseconds before converting an
-        IDE selection into Visual mode.
-
-        Some IDE features make a selection to help modify text (e.g. backspace
-        in Python or Yaml selects an indent and invokes the "remove selection"
-        action). IdeaVim listens for changes in selection to switch to Visual
-        mode, and will return to Normal mode when the selection is removed,
-        even if originally in Insert mode.
-
-        By waiting before converting to Visual mode, temporary selections can
-        be ignored and the current Vim mode maintained.
-        
-        It is not expected that this value will need to be changed.
