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.
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 + . This allows me to quickly return to the top of the webpage. You can consider using this setup.
