Windows 10 Touch Long Press

[mole]

So I've googled the TG%$T out of this and cannot find a solution so....

 

 

I have a surface Go, windows 10 and I need to try and get a long press via touch. It works with a mouse - a long left click.

 

 

Reason being I have touch panels running and a long press allows different commands to run.

 

So far I have tried, disabling right click on long press, changing the Touchmode_hold registry settings.

 

thanks
