--- title: Select all category: features --- {@snippet features/build-select-all-source} The {@link module:select-all/selectall~SelectAll} feature allows selecting the entire content of the editor using the Ctrl/⌘+A keystroke or a toolbar button. ## Demo Press Ctrl/⌘+A or use the toolbar button to select the entire content of the editor. Note that when editing an image caption, the selection will only expand to the boundaries of the caption. {@snippet features/select-all} ## Installation This feature is enabled by default in all builds (loaded by the {@link module:essentials/essentials~Essentials} plugin). The installation instructions are for developers interested in building their own, custom rich text editor. To add this feature to your editor, install the [`@ckeditor/ckeditor5-select-all`](https://www.npmjs.com/package/@ckeditor/ckeditor5-select-all) package: ```bash npm install --save @ckeditor/ckeditor5-select-all ``` Then add the `SelectAll` plugin to your plugin list: ```js import SelectAll from '@ckeditor/ckeditor5-select-all/src/selectall'; ClassicEditor .create( document.querySelector( '#editor' ), { // Load the plugin. plugins: [ SelectAll, ... ], // Display the "Select all" button in the toolbar. toolbar: [ 'selectAll', ... ], } ) .then( ... ) .catch( ... ); ``` ## Common API The {@link module:select-all/selectall~SelectAll} plugin registers the `'selectAll'` UI button component and the `'selectAll'` command implemented by {@link module:select-all/selectallcommand~SelectAllCommand}. The command can be executed using the {@link module:core/editor/editor~Editor#execute `editor.execute()`} method: ```js // Select the entire content of the editor. editor.execute( 'selectAll' ); ``` We recommend using the official {@link framework/guides/development-tools#ckeditor-5-inspector CKEditor 5 inspector} for development and debugging. It will give you tons of useful information about the state of the editor such as internal data structures, selection, commands, and many more. ## Contribute The source code of the feature is available on GitHub in https://github.com/ckeditor/ckeditor5-select-all.
