+description: We are always looking for ways to make Directus Studio more accessible. Here are some of the methods we currently support.
+title: Accessibility
+---
+
+
+## Keyboard Navigation
+
+You can navigate through Directus Studio entirely with your keyboard. The Skip Menu makes it easy to jump between page sections.
+
+### Shortcuts
+
+- Navigation is primarily done with the `Tab` key and occasionally with the arrow keys.
+- Enter your selection with the `enter` or `space` keys.
+- Save with `meta` + `s`.
+- Apply edits in modals/drawers/popovers with `meta` + `enter`.
+- Cancel/exit modals/drawers/popovers with the `escape` key.
+
+Special shortcuts for the TinyMCE/WYSIWYG Editor:
+
+- `alt` + `F10` Focus/jump to toolbar
+- Arrow Keys: Navigate left/right through toolbar
+- `Esc`: Return to the editor content area
+

+
+### Things to keep in mind
+
+- Visual Editor is only accessible on the Directus side — not your website. So we always need to click an edit button first, then the
+  overlays are accessible.
+- Manual Sorting is currently not supported/accessible.
+- The DateTime interface is currently not supported/accessible.
+- Once focused, the code interface (Codemirror) cannot be exited using the tab key.
+- The Markdown interface also doesn’t allow you to exit the field. This is because it supports tabs inside the editor’s
+  text content.
