Tablets
Here are some tips to improve your Rumba experience using a tablet.
Set the Use Tablet setting
This version of Rumba may not automatically detect your tablet (especially on Windows). To enable Rumba’s tablet features manually, check General -> Use Tablet.
Input Deadzone
Tweak the input device deadzone to make the selection easier with a tablet.
For that, edit the General -> DeadZone Radius property. 12 is a good value to start with.
Selection Keyboard Shortcut
It is also possible to select in the Rumba viewport using a shortcut, G by default.
