Currently when I write using a pen tablet ( like Wacom/ XP-pen), it takes pen input (writing) and when I use mouse it takes scroll function ( drag and move the page).
I want to scroll ( drag and move the page) using my pen tablet also because switching between mouse and pen again and again is very inconvenient.

For that I request you to provide a hand tool, which on being selected drag and move the page. I have attached an image of open board which has similar tool.
