+- 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).

-   * During vim initialization process, it firstly loads the .vimrc file, then executes scripts from the plugins folder.
-   * This practically means that the .vimrc file is initialized first, then the plugins are loaded.
-   * See `:h initialization`
+   * See the docs for [VimExtension.init]
    *
    * In IdeaVim we don't have a separate plugins folder to load it after .ideavimrc load. However, we can collect
    *   the list of plugins mentioned in the .ideavimrc and load them after .ideavimrc execution is finished.
-   *
-   * Why this matters? Because this affects the order of commands are executed. For example:
-   * ```
-   * plug 'tommcdo/vim-exchange'
-   * let g:exchange_no_mappings=1
-   * ```
-   * Here the user will expect that the exchange plugin won't have default mappings. However, if we load vim-exchange
-   *    immediately, this variable won't be initialized at the moment of plugin initialization.
-   *
-   * There is also a tricky case for mappings override:
-   * ```
-   * plug 'tommcdo/vim-exchange'
-   * map X <Plug>(ExchangeLine)
-   * ```
-   * For this case, a plugin with a good implementation detects that there is already a defined mapping for
-   *   `<Plug>(ExchangeLine)` and doesn't register the default cxx mapping. However, such detection requires the mapping
-   *   to be defined before the plugin initialization.

-    // These additional interactive editors are not file-based, but must have a writable document. However, log output
-    // documents are also writable (the IDE is writing new content as it becomes available) just not user-editable. So
-    // we must also check that the editor is not in read-only "viewer" mode (this includes "rendered" mode, which is

-    // Finally, we have a special check for diff windows. If we compare against clipboard, we get a diff editor that is
-    // not file based, is writable, and not a viewer, but we don't want to treat this as an interactive editor.
