+# Date/Time Clipboard Shortcuts Setup
+
+This replaces espanso with a cleaner clipboard-based solution that won't trigger "Updated keyboard layout" notifications.
+
+## How It Works
+
+Instead of text expansion, keyboard shortcuts copy the formatted date/time to clipboard. You then paste with `Ctrl+V`.
+
+## Available Formats
+
+- **wd**: ISO week.day (e.g., `52.4`)
+- **3t**: 360-time division (e.g., `331`)
+- **uid**: Random UUID 8 chars (e.g., `a8b9bf0a`)
+
+## GNOME Keyboard Shortcuts Setup
+
+1. Open Settings → Keyboard → Keyboard Shortcuts (or run: `gnome-control-center keyboard`)
+
+2. Scroll to bottom and click "+ Add Custom Shortcut"
+
+3. Add three shortcuts:
+
+### Shortcut 1: Week Day
+- **Name**: `Copy Week.Day`
+- **Command**: `/home/mariano/wdir/dm/dmapp/dmos/datetime-clipboard.py wd`
+- **Shortcut**: `Ctrl+Super+W`
+
+### Shortcut 2: 360-Time
+- **Name**: `Copy 360-Time`
+- **Command**: `/home/mariano/wdir/dm/dmapp/dmos/datetime-clipboard.py 3t`
+- **Shortcut**: `Ctrl+Super+T`
+
+### Shortcut 3: UUID
+- **Name**: `Copy UUID`
+- **Command**: `/home/mariano/wdir/dm/dmapp/dmos/datetime-clipboard.py uid`
+- **Shortcut**: `Ctrl+Super+U`
+
+## Usage
+
+1. Press the keyboard shortcut (e.g., `Ctrl+Super+W`)
+2. Paste with `Ctrl+V` wherever you need it
+
+## Advantages Over Espanso
+
+- No keyboard layout notifications
+- Works reliably on Wayland
+- Simpler architecture (no daemon running)
+- More control over when to paste
+- Works in password fields and other protected inputs
+
+## Removing Espanso (Optional)
+
+If you want to fully switch away from espanso:
+
+```bash
+# Stop espanso service
+espanso stop
+
+# Disable autostart
+espanso service unregister
+
+# Uninstall (if desired)
+# sudo apt remove espanso  # or however you installed it
+```
+
+## Testing
+
+```bash
+# Test each format
+/home/mariano/wdir/dm/dmapp/dmos/datetime-clipboard.py wd
+/home/mariano/wdir/dm/dmapp/dmos/datetime-clipboard.py 3t
+/home/mariano/wdir/dm/dmapp/dmos/datetime-clipboard.py uid
+
+# Then paste to verify clipboard contents
+```
+
+## Cross-Platform Notes
+
+This solution is part of the deskmeter cross-platform configuration effort:
+
+- **Linux (Wayland/X11)**: Uses `wl-copy` or `xclip` for clipboard
+- **Windows**: Would require AutoHotkey or similar for global shortcuts
+- **macOS**: Would use `pbcopy` for clipboard
+
+The core datetime logic is platform-independent Python. Only clipboard mechanism needs platform-specific handling.
