Is there an east touchpad toggle Leap 15.2?

I’m tearing my hair out trying to use Libre Office Writer on an HP laptop. I touch type and constantly have unintended mistyped content because it’s impossible to not hit the touchpad with my hands. I need the cursor movement functionality available, so going into setup every time I want to activate or deactivate it is not practical? I’ve searched a fair amount fir a solution but haven’t found one. Is there any way to have a function key, or sone kind of hot key to accomplish thus? Thanks Jim Thus spake iPad.
