The shortcut key for opening a Dell computer touchpad is usually achieved through a combination of keys, but the specific function key used in combination with the Fn key may vary depending on different Dell laptop models. Here are some common methods and suggestions: 1. Common shortcut key combinations
Fn + F3： Some Dell laptops may use this key combination to turn on or off the touchpad.
Fn + F5： This is also a possible combination key, depending on the laptop model.
Fn + F9： On some Dell laptops, this key combination may be used to control the touchpad.
Fn + F12： Another possible combination key is used to turn on or off touchpad functionality.
Due to the fact that different models of Dell laptops may use different combinations of function keys and Fn keys, if the above combination keys do not work on your laptop, you can try holding down the Fn key and testing the F1 to F12 keys one by one until you find the key that can control the touchpad switch. 2、 Open the touchpad through system settings
If the shortcut key cannot open the touchpad, you can also try enabling it through system settings:
1. Click the "Start" button on the taskbar and select the "Settings" icon (gear shaped).
2. In the settings window, select the "Devices" option.
3. Find and click on the "touchpad" settings.
4. On the right side, you should be able to find an option to turn on or off the touchpad. 3、 Precautions
Before using shortcut keys, please ensure that your Dell laptop has installed the corresponding touchpad driver and Fn hotkey driver, otherwise shortcut keys may not work properly.
If your Dell laptop has a specific touchpad switch button (usually located in the F-key area or side of the keyboard), make sure that the button is not locked or disabled.
The shortcut key for opening the Dell computer touchpad may vary by model, but it can usually be achieved by combining the Fn key with a certain function key. If the shortcut keys do not work, you can try enabling the touchpad through system settings.
