What are these Keyboard Shortcut keys?

[YoYoMa]

These show up all over macOS as keyboard shortcut keys, but I have no idea what they are or how to press them. Anyone here know? Thanks!

Those symbols are for Page Up, and Page Down, respectively.

You can see those on this page, along with a lot of other keyboard symbols.
