The popup lists and overlay lists such as Goto Anything, Command Palette should support Page Down and Page Up keys. Currently they do not. I mean, nothing happens when either Page Down or Page Up is pressed.
Though, in case of long lists, such as Goto Anything and Command Palette, the ability to go through items by pages rather than item by item is fishing for existence. Just because it’s handy and faster.
There are at least two existing topics already created:
- Page-up/down in autocomplete popup and command palette?
Why it is not supported yet?
