Scroll to top/bottom

Is there a way to set keyboard shortcuts to scroll to top/bottom for all apps (i.e., a system shortcut), or at least for Finder?

In macOS 15.1 Sequoia, this is set to Fn-Left, Fn-right. I want it set to Cmd-up and Cmd-down. To compound matters, those keystrokes are assigned by MacOS to other actions.

Is this what are you looking for:

could you share where it is in system settings?

Currently, my browser is set up so that when I double-click the left mouse button at the left edge of the screen, it maps to fn + :arrow_up:. This allows me to quickly return to the top of the webpage. You can consider using this setup.

Can't it be remapped in system settings of keyboard

It seems that this option is not available in the menu bar.
