### Altium Designer PCB Routing View Shortcut Keys In the context of using Altium Designer specifically for PCB routing, several shortcut keys enhance efficiency and control during design tasks. These shortcuts are categorized based on their functionality within the PCB editor. #### General Navigation Shortcuts For navigating around the workspace effectively while performing routing operations: - **Pan**: Press `Spacebar` followed by an arrow key to pan the view in that direction. - **Zoom In/Out**: Use `Page Up` or `Page Down`. Alternatively, holding down `Ctrl` and scrolling the mouse wheel also adjusts zoom levels[^1]. #### Interactive Routing Commands To initiate and manipulate interactive routing processes efficiently: - **Start Interactive Routing**: Press `R`. - **Switch Layer During Route**: While routing, press `L` to cycle through available layers. - **Toggle Between Track and Arc Segments**: Press `A` when placing tracks to switch between straight segments and arcs. #### Editing Existing Routes When modifying existing routes or connections already placed on the board: - **Cut Selected Tracks/Wires**: Select objects then press `Delete`. - **Tear Drop Creation**: After selecting a via or pad, pressing `D`, `T` will open tear drop creation options. #### Miscellaneous Useful Shortcuts Additional commands useful for various aspects of working within the PCB layout environment: - **Show All Objects Under Cursor**: Press `Shift+C` which can help identify overlapping items under cursor location. - **Lock Object(s)**: With object selected, press `Alt+L` to lock it preventing accidental movement or modification. ```python # Example Python code demonstrating how one might simulate sending these keystrokes programmatically (for educational purposes only) import pyautogui as pg def send_routing_shortcut(command): if command == "start": pg.press('r') elif command == "switch_layer": pg.press('l') send_routing_shortcut("start") # Starts interactive routing mode ```
