Problem solved, it was just a technicality.

This applies only to the pen if you have enabled "Press and hold" for "Right-click" in Control panel->Pen and Input Devices->Pen options.

Nevertheless, there is a technical way to tell the system that an application locally does not want "Press and hold" to be interpreted as a right click. I was able to use it successfully for Fitaly so my concern that this option would interfere with the key repeat functionality that we want to introduce has gone. :-)

The key repeat functionality will be optional, you will be able to toggle it on or off and the the key repeat delay will be configurable too.

Best regards.
