On macOS we can set our own shortcuts to most application using the System Preferences > Keyboard Shortcuts> Application Shortcut tab.

This is a basic accessibility requirement to my mind, and if it doesn't exist already, it needs to exist.

But there needs to be Menu Bar commands in the Acrobat Menus to actually hook to that function in the first place. Far as I can tell Acrobat doesn't have menu commands to do that.

All the other Adobe apps I use in Creative Cloud suite (most of them) have a a command for that (shortcut "`"/"~" keys) but I prefer those used in browsers etc and Finder itself for that matter(!) "{" left "}" right because it's an easier combo than dropping the Shift key in and out.

Is there somewhere else to do FR, for exmaple some apps like InDesign has a seperate forum for devs, beta users and FRs.

EDIT>
I found out on the Adobe community forums that 'control' + 'tab' cycles through document windows, but it would be good to have menu hooks for it in addition to actually making it obvious that 'control' + 'tab' is a thing. Its unconventional for Mac software to use the control key for shortcuts (its a windows thing) except in 3D apps and the like where they literally have hundreds of shortcuts for tools and processes.
