Enable Note Operations via Keyboard Shortcuts

The iOS version of Simplenote allows users to perform various note-related actions through Shortcuts, such as creating a new blank note, appending content to an existing note, or searching for notes with specific content. These features enable users to complete tasks without opening the Simplenote app interface.

I would love to see similar functionality implemented in the desktop version of Simplenote, allowing users to manage notes using keyboard shortcuts.

Ideally, pressing a specific shortcut (e.g., Ctrl+Shift+C) could instantly add the clipboard content to a new note or append it to a selected note. Additionally, if a user chooses to add clipboard content to a new note, the note title should be configurable in advance—it could be a fixed text or a variable, such as the current timestamp.

The issue names no files, tests, or entry points. Start by locating the desktop keyboard-shortcut handling and note creation, append, and search flows, then review how the iOS Shortcuts behavior maps to the requested desktop actions. Done should include an agreed shortcut and configuration design for clipboard targets and note titles.
