# Notes & Annotations Void ships a **browser-local** note layer. Open the notes panel and save lightweight sticky notes; they persist in your browser across reloads and are **global** — they appear on every page. Notes are never sent to a server. ## Adding a note 1. Open the **Notes** panel (bottom-left button, or `Ctrl/Cmd` + `Shift` + `N`). 2. Press **+ Add note**. 3. Pick a color, type your note, press **Save**. ## The Notes panel The sidebar lists all your notes, each showing a color bar, the note text, and its date: - **+ Add note** — compose a new note inline. - **Edit** — reopen the note in a prefilled editor and save changes. - **Delete** — removes a note. - **Export .md** — downloads all notes as Markdown. - **Export .json** — downloads them as JSON (good for backup/migration). Notes are **global**: they are not scoped to any single page, so you see the same set from anywhere on the site. ## Keyboard shortcuts - `Ctrl/Cmd` + `Shift` + `N` — toggle the notes panel. - `Ctrl/Cmd` + `Shift` + `B` — toggle the navigation sidebar (state is remembered). - `Ctrl/Cmd` + `Shift` + `T` — toggle the "On this page" table of contents (state is remembered). - `Esc` — close the panel (or cancel the composer). ## Storage & retention Notes are stored in `localStorage` (`void-notes`). Each note has a timestamp and is **automatically purged after 3 days** (default). Because storage is per-browser, your notes don't travel between devices. ## Configuration Control the feature from `mkdocs.yml`: ```yaml theme: void: notes: true # disable to turn off the whole feature notes_ttl: 259200000 # retention window in milliseconds (3 days) ``` ## Privacy All data stays in your browser — no network requests are made by the notes feature.
