How can I add / enable virtual Ctrl & Shift button in android version
You probably don’t. I have long process press for strg so the color picker and for shift, there is a preference to set your stylus button.
So when you press and drag the brush size changes.
Although on android I activate the brush tilt function to change the size.
Could it be that you meant “a long press” instead of “a long process”?
