Choose **Record Shortcut…** and press a combination containing Command, Option, or Control.

 The Applications shortcut always targets the application launcher, not the last-used tool. Command shortcuts open their selected tool directly. Pressing a shortcut while its destination is already frontmost dismisses Conjure; switching destinations opens a fresh view. Active confirmations and uninstall operations are not interrupted. All global shortcuts pause while recording and resume afterward. Conjure rejects shortcuts already assigned to another destination or used by its own menus and navigation.

 The picker works offline with 1,870 emoji from [gemoji v4.1.0](https://github.com/github/gemoji/tree/v4.1.0). Its [MIT license](Sources/ConjureKit/Resources/LICENSE-gemoji.txt) is included in the application.
 
+## Notes
+
+Search for **Conjure Notes**, or assign it a global shortcut in Settings. **New Note** (Command-N) creates a note; the menu switches between notes, and reopening Notes restores the last selection. Each note’s first nonempty line becomes its menu title.
+
+Edit Markdown directly: headings, bold, italic, lists, links, inline code, and fenced code blocks are highlighted while the source remains visible. Paste images or use **Insert Image…** to embed a local image. Command-Z undoes edits; Command-Shift-Z redoes them. Undo history is cleared when switching notes so edits cannot spill into another note.
+
+Notes autosave locally as RTFD packages, including embedded images, under `~/Library/Application Support/Conjure/Notes`. No account, network access, or cloud sync is involved. Save failures appear below the editor and prevent switching, closing, or quitting until saving succeeds, preserving the unsaved buffer. The Back chevron restores the launcher search; Escape or Command-W dismisses Conjure.

 ## Translation
 
 Search for **Conjure Translate** and open it. Enter English in the search bar, choose a provider, then press Return or click **Translate**. Typing alone never sends text. Copy selected Japanese output with Command-C; the copy hint appears beside the Translate action at the bottom. The Back chevron beside the input returns to the launcher and restores your search; Escape dismisses Conjure.
