What is the quickest most universal way to open a URI in a Chromium-based freeware web browser?

I have all my Chromium-based freeware browsers set to open to multiple
blank tabs, where the last page opened to is this one:
o Iron chrome://settings/clearBrowserData
o Opera opera://settings/clearBrowserData
o Epic chrome://settings/clearBrowserData
etc.

That URI is also set as a bookmark but not as a home page.
o Where, for example, Epic, doesn't seem to be able to set a home page.

The problem is, after a while of use, that specific URL is no longer a page
being displayed - but you want to display it to click the button every once
in a while.

Given, for real estate reasons, I have no "toolbars" or icons set up that I
can't delete, all I really want is a keyboard combination that works for
all Chromium-based freeware browsers, that opens to that specific page.

I'd like to click the keyboard every once in a while to clear contents.
o What's the quickest way to do that in all Chromium-based browsers?

I looked here first...

https://blog.hubspot.com/sales/chrome-keyboard-shortcuts
etc.

If I set it as the home page in every browser, ALT+HOME will work...
o But not every browser (apparently) allows you to set a HOME page.

Is there a keyboard solution that doesn't require it to be the HOME page?

Arlen,

How come you have already discovered that not all chromium-based programs
are the same (case in point: epic, homepage), but still seem to think that
all of them should have hotkeys as well as the same actions to them defined
? That doesn't really make much sense you know.

Besides, how many people do you think that exist that have-and-use Iron,
Opera, Epec, etc and have therefore a chance to know what /the/ hotkey for
it, if any, for all those browsers is ? Even with just the first three
you are asking for a small subset of users, and with the "etc" at the end a
subset nearing to an absolute zero.

Maybe just show a list with the chromium-basted browsers you are interrested
in and ask if any reader who uses one of them to mention the hotkey, if any,
which does what you want. That should make it easy for you to figure out
if such a hotkey exists or not.

P.s.
You could perhaps create a shortcut (to the browser) which opens that
"clearBrowserData" page - assuming that all chromium-based browsers allow
opening a webpage that way ...
