Display Settings Shortcuts Needed

Because of my vision I need to quickly change display setting between 125, 150, and 175 as well shifting between portrait and landscape orientation -- all without having to call up the Display Settings page.

Example. I need 175% to clearly see the file tree but that is too much for web browsing. There I use 125 or 150%.

Some web pages do not adjust for portrait. Clipping from the right and left is common. The only solution is to turn the monitor, a 23 or so inch HP that pivots on a stand, and change the orientation in the Display panel settings. This is a BIG pain. Reducing Firefox magnification restores the edges, but the letters are too small to read easily.

I have not been able to find a method for creating such shortcuts on the web.

Does anybody have any suggestions?

All comments and suggestions will be welcome.

One option is to set the OS resolution and use NoSquint extension for Firefox.

If NoSquint is not available as a WebExtension, an alternative is to migrate away from Firefox to a fork that allows NoSquint. With NoSquint, page and font size can be set globally and per site.

I use this extension with PaleMoon; Basilisk, also from the same forker, is approximately more closer to Firefox, but is pre-Firefox 57 and its WebExtension requirement.

I need the highest resolution and sharpest possible. That is why I purchase the HP monitor ( I am thinking about a 4K one).

The magnifier works but it is clumsy and awkward.
Scripts and registry changes sound risky, and beyond my competence.
I installed the current no squint but could not get the right click to work.

Sounds like there is no balancing the size of the file tree and the FF browser?

I hate IE but would it work better that FF for my problem?

This is an accessibility issue. Does anyone know how I can get this in front of Microsoft?

As for the "The only solution is to turn the monitor, a 23 or so inch HP that pivots on a stand, and change the orientation in the Display panel settings" part, used to be desktop publishing such as newspapers used such a monitor, don't know if they are still made. There may be the attachments to fasten a monitor to a desk would have that function, I'd check Staples or OfficeDepot/OfficeMax [one owned by the other].

A desktop publishing program I like is Serif PagePlus.

Code:

I installed the current no squint but could not get the right click to work.

With PaleMoon, a Firefox fork, NoSquint puts an icon somewhere on the browser window to be accessed to adjust the zoom settings.

I don't ever use context-menu to access such settings. But then again, I use menu wizard extension to remove many context-menu options.

If NoSquint still doesn't work, then the default zoom capability, CTRL+scrolling wheel, can mitigate some of the negative visual impacts.
