How to toggle pointer size with a hotkey on Mac?

I would like a variable sized pointer (cursor) but have been unable to find a way of accomplishing it so I have compromised by making my pointer larger permanently.

As can be seen in the screenshot I have set the Pointer size slider about a third the way across the scale. This gives a larger, clearly visible cursor without it being obtrusive.

I have also given it a white outline to make it more visible against awkward/dark backgrounds.

the main feature provided without any add-on is

Settings > Accessibility > Display > scroll way down to 'Pointer'

...enable "shake Mouse Pointer to locate"

Then when you shake the mouse pointer, the cursor on the screen grows much larger for a moment, then returns to normal size.

Please Clarify your Post:

A "hotkey" is a keyboard shortcut. As for your word "pointer", are you referring to the word "cursor"?

Increasing the Cursor Size when Hovering Over a Hyperlink:

If you want the cursor to increase-in-size, when ohvered over a hyperlink on a Web browser or anywhere else (i.e. in a MS Word Document), then note that is not an option built in to your Mac --not even an Accessibly feature. However, there may be an add-on you can use; just be cautious as to where you get it.

Recommend this to Apple:

Shake mouse pointer to locate:

1. Go Here: Make the Pointer Easier to Dee on Mac - Apple Support
2. As it Reads: Shake mouse pointer to locate: Turn this option on to make the pointer larger when you quickly move your finger on the trackpad or quickly move the mouse.
