**Can't make a two-key shortcut**

There’s this nice feature that lets users to make their own keyboard shortcuts and it’s pretty useful.
I want to add a shortcut to use next page feature and want it to be alt + page down
The Problem I’m having is the fact that when I press alt it makes the shortcut alt and when I press page down it makes the shortcut page down.
Is there a way to make two-key shortcuts or I just couldn’t figure it out?

Brave Version(1.78.102):

@Mori are you continually holding it down? If you’re just pushing one button at a time, that’s your issue. Like you said, if you press Alt it’s seeing it as just Alt. If you press only Page Down, then that’s it. You must keep both pressed down at the same time for it to register the combo.
