-/**
- * Action holder for IdeaVim actions.
- *
- * [implementation] should be subclass of [EditorActionHandlerBase]
- *
- * [modes] ("mappingModes") defines the action modes. E.g. "NO" - action works in normal and op-pending modes.
- *   Warning: V - Visual and Select mode. X - Visual mode. (like vmap and xmap).
- *   Use "ALL" to enable action for all modes.
- *
- * [keys] comma-separated list of keys for the action. E.g. `gt,gT` - action gets executed on `gt` or `gT`
- * Since xml doesn't allow using raw `<` character, use « and » symbols for mappings with modifiers.
- *   E.g. `«C-U»` - CTRL-U (<C-U> in vim notation)
- * If you want to use exactly `<` character, replace it with `&lt;`. E.g. `i&lt;` - i<
- * If you want to use comma in mapping, use `«COMMA»`
- * Do not place a whitespace around the comma!
- *
- *
- * !! IMPORTANT !!
- * You may wonder why the extension points are used instead of any other approach to register actions.
- *   The reason is startup performance. Using the extension points you don't even have to load classes of actions.
- *   So, all actions are loaded on demand, including classes in classloader.

- * After creating some functionality you can understand that IdeaVim has a bit different behavior, but you
- *   cannot fix it right now because of any reason (bugs in IDE,

- *   In that case, you should NOT remove the corresponding test or leave it without any marks that this test
- *   not fully convenient with vim, but leave the test with IdeaVim's behavior and put this annotation
