Thanks for everyone voted, I forgot to include the trackball option. Apologies.
Here is a small update, maybe helpful for anyone in the future.
I dropped my Huion large tablet expectations, price was quite big for my budget for experimenting and online opinions were divided.
Most positive comments were posted (amazon etc) by people like me that never have used another pen tablet in the past.
A second reason was that Youtube have some videos that indicate that (maybe, I cannot know for sure) some brands push biased positive reviews.
A third subjective reason was brand recognition. Wacoms are around for years and (seem) to have more stable software and proven durability.
I like the battery free pens but I am not confortable with bluetooth (kid also using laptop) and rechargeable batteries if not necessary.
Ended up to a smaller Wacom One (CTL-672-S medium) that seems quite enough for a newbie like me.
It was easy to use by day one, didn't actually messed everything as some people claim while switching from mouse.
Mouse is still connected to the laptop, i have a hard time to highlight and c/p text. If anyone have a solution I would be grateful to read it.
Although it is a comsumer model, seems working fine, configured it for one screen it was fuzzy switching on two monitors.
For second screen I use the mouse to usually leave open email or a tutorial.
Guess for two monitor setup if no masking needs exist, one can drag the Program tab and have a large preview
and keep all other tabs (timeline / effect controls / lumetri etc etc) in monitor one working on them with the tablet.
Working on a 27" monitor, "medium" tablet is actually "big". I mean gives space and detail to move around.
hand still moves. Guess a better configuration of program tabs is needed.
As for video editing if this helps works (guess) as a mouse with Pr and i find my hand sitting in one position more comfortable.
Masking still is horrible, you cannot set clicks one near other in "fit window" mode, thought that was a mouse limitation, but no.
Quite odd but tablet didn't fit in front or next to the keyboard, rather rotated around 35-40 degrees. Perhaps due to my wrong sitting position.
Actually the pen helps using more the keyboard as long as it accelerates the process.
Wacom One have no tablet keys, but on the pen has two buttons.
If this helps, for stock (Pr) it was easy to configured them as "extract a frame" (Ctrl+Shift+E) and "Export" (Ctrl+M) keystrokes.
Bonus feature, the little one can draw better with the pen in Windows painting. I was amazed to see how easily adopted it and used it to open Paint.
Not sure if Windows or Wacom driver enables it but while saving a file, clicking on the name tab appears a free writing tab
where with the pen you can hand write e.g. "test" and reads it and saves the file as eg "test.mp4"
It also tolarates and seems to support copying from a paper, I mean putting the paper over the tablet and pushing over lines if this helps.
Offtopic: I use to say that I suck at photography.
Now on I know that I am confirmed to suck at photography
and painting - free hand drawing
EDIT: still using keyboard with two hands for keystrokes, easy to flip the pen as a ...normal pen and type.
People (guess) won't mess with the timeline, that's basic if you are editing with someone over your shoulder giving instructions.
Puttong the pen down and clipping it to the tablet holder, psychological dictates "end of work" not like mouse "oh, let's also do this or that".
Pen does support scrolling (eg webpage). That was something I wondered and found no answer online.
Not sure if applies to everyone but Win10 by default set pen to "left" hand, guess affecting tilt options. Had to change to "right"
Apologies but I don't use photo editing or illustrating programs to share an opinion.
Hope to revise this post with more video editing comments in teh future.
