This is an extremely basic question, but I haven't found an answer yet.

I recently purchased a brand-new computer with Windows 10 and at the moment am using the Microsoft Edge browser that came with it.

I would like to open some offline (HTML) pages, but the Control-O feature to which I am accustomed in IE, Chrome, and Firefox, doesn't work. In the Edge browser, the hotkey Control-O resets the zoom level.

Is there a replacement hotkey for Control-O in Microsoft Edge?
Alternately, what is the non-hotkey method for opening an offline page in Edge?

Note, I am not trying to set the default Start page. I would simply like a quick and easy way to navigate to and open an HTML page that is saved on the hard drive.
