What is the use case for keyboard shortcuts on handheld devices?

On desktops/laptops, keyboard shortcuts save reaching for a mouse, aiming (on the relativley large screen), and clicking. On handhelds, I don't think it's faster to use a shortcut than to simply tap something an inch away.

Also, on handhelds, the keyboard blocks a significant part of the screen. And keyboard shortcuts typically use accelerator keys, which are hard to use on handhelds.

Do you use Android with a physical keyboard?

I have a physical keyboard for my foldable. Works great, except that keyboard shortcuts don't typically work as expected.

Could be referring to a physical keyboard attached to an iPad
