Is using Mousekeys with the Pencil Tool a well-known thing?

[William Overington]

I have found that when using the Affinity Designer Pencil Tool on a Windows system on a laptop computer that using Mousekeys on an external keyboard to press down and effectively hold down the trackpad by software rather than hold it down physically makes drawing with the Pencil Tool much better. It means that I can lift my finger from the trackpad without ending the curve that is being drawn by the Pencil Tool.

Is this already widely known about or is it a new idea?
