I have a Windows 10 laptop (Dell XPS 17) on which a few of the keys have stopped working properly. I therefore have bought a replacement external keyboard (Logitech G710+) for home use.
When I travel with the laptop, I'll still use the broken keyboard. When at home, I'll use the external keyboard.
I want to place the external keyboard on top of the laptop keyboard, but the problem is that then some keys will be hit inadvertently. Therefore I'd like to a convenient way of turning the laptop keyboard on and off.
There's a superficially similar question here but it's different because there the OP was willing to accept the permanent disabling of the laptop keyboard via the uninstallation of the driver.
