windows 10 – How can I change the Alt+7 shortcut in microsoft edge?

I sometimes like to use these quotation marks: „“ Since my keyboard does not have these (the standard quotation marks are “), I enter them using their unicode code. When I do this in my browser (Microsoft edge), for „ this works fine as I can just enter Alt+0132 on my numpad. For the “ character however, the code would be Alt+0147. When I do this in edge, Alt+7 goes to the “new tab” page and the site that I was on before is closed.

How can I change this behaviour?
