+# Keyboard Shortcuts
+
+TheChart application supports comprehensive keyboard shortcuts for improved productivity and efficient navigation.
+
+## File Operations
+- **Ctrl+S**: Save/Add new entry - Saves the current entry data to the database
+- **Ctrl+Q**: Quit application - Exits the application (with confirmation dialog)
+- **Ctrl+E**: Export data - Opens the export dialog window
+
+## Data Management
+- **Ctrl+N**: Clear entries - Clears all input fields to start a new entry
+- **Ctrl+R** or **F5**: Refresh data - Reloads data from the CSV file and updates the display
+
+## Window Management
+- **Ctrl+M**: Manage medicines - Opens the medicine management window
+- **Ctrl+P**: Manage pathologies - Opens the pathology management window
+
+## Table Operations
+- **Delete**: Delete selected entry - Deletes the currently selected entry in the table (with confirmation)
+- **Escape**: Clear selection - Clears the current selection in the table
+- **Double-click**: Edit entry - Opens the edit dialog for the selected entry
+
+## Help
+- **F1**: Show keyboard shortcuts help - Displays a dialog with all available keyboard shortcuts
+
+## Implementation Details
+
+### Menu Integration
+All keyboard shortcuts are displayed in the menu bar next to their corresponding menu items for easy reference.
+
+### Button Labels
+Primary action buttons show their keyboard shortcuts in the button text (e.g., "Add Entry (Ctrl+S)").
+
+### Case Sensitivity
+- Shortcuts are case-insensitive
+- Both `Ctrl+S` and `Ctrl+Shift+S` work
+- Uppercase and lowercase variants are supported
+
+### Focus Requirements
+- Keyboard shortcuts work when the main window has focus
+- Focus is automatically set to the main window on startup
+- Shortcuts work across all tabs and interface elements
+
+### Feedback System
+- All operations provide feedback through the status bar
+- Success and error messages are displayed
+- Confirmation dialogs are shown for destructive operations (quit, delete)
+
+## Usage Tips
+
+### Quick Workflow
+1. **Ctrl+N** - Clear fields for new entry
+2. Enter data in the form
+3. **Ctrl+S** - Save the entry
+4. **F5** - Refresh to see updated data
+
+### Navigation
+- Use **Ctrl+M** and **Ctrl+P** to quickly access management windows
+- Use **Delete** to remove unwanted entries from the table
+- Use **Escape** to clear selections when needed
+
+### Getting Help
+- Press **F1** anytime to see the keyboard shortcuts help dialog
+- All shortcuts are also visible in the menu bar
+- Button tooltips show additional keyboard shortcut information
+
+## Accessibility
+- Keyboard shortcuts provide full application functionality without mouse use
+- All critical operations have keyboard equivalents
+- Shortcuts follow standard application conventions (Ctrl+S for save, Ctrl+Q for quit)
+- Help system is easily accessible via F1
