Can one -click to allow the Indesign screen to live in the middle, and the layout is enlarged to 80%

It is not necessarily 80%, but my computer is just 80%displayed for the screen.
Not big or small, it looks just right.

Hello, great M1B.
It's amazing, it turns out that you have always existed.

Use script? It should be ok.
If the screen amplification multiple is 80%, the coordinate origin of the sitting angle is set to x = 0, y = 0.
If the X direction can be controlled, the position of the Y direction rolling bar is good.

Another thing,This is more practical. The above is just a good vision. If Adobe can see the best improvement:

Last time, the issue of alignment of leadership list. There is a little problem, please take a look.
It is the first position with a full -angle colon (：) alignment, The final script is invalid for the colon.
