Office Hotkeys plugin

A new plugin that displays a keyboard-shortcut cheat sheet for Microsoft Excel, Outlook, and PowerPoint — a glanceable, rotating reference for the e-ink display.

What it does

• Per-instance settings: App (Excel / Outlook / PowerPoint) and Skill level (Beginner / Intermediate / Advanced).
• Each refresh shows one themed category of shortcuts (Navigation, Formatting, Formulas & Functions, …), rotating hourly so the display stays fresh.
• Skill level is a difficulty floor — it shows shortcuts at your level and harder, topping up with the next level down only when a category is thin, so an Advanced screen stays advanced-first and never shows trivial shortcuts.
• Weighted-random selection picks a highlighted "top move" plus a list of shortcuts; content reshuffles each refresh.
• Bundled, curated Windows-shortcut dataset (data/shortcuts.json) — no external API or network access required.

Implementation

• Follows docs/building_plugins.md: OfficeHotkeys(BasePlugin) with generate_image / generate_settings_template, render/ HTML + CSS via render_image, plus settings.html, icon.png, and plugin-info.json.
• The selection logic (selection.py, constants.py) is pure and stdlib-only, kept separate from rendering, with pytest unit tests in tests/.
• Designed for the 6-colour Spectra e-ink palette — flat, high-contrast.

Testing

• Unit tests cover category rotation, the skill-level floor + top-up, and weighted selection.
• Verified on hardware — Raspberry Pi Zero 2 W with an Inky Impression 7.3" (800×480) — rendering correctly for all three apps across skill levels.
