Ability to change cmd+left/right shortcut to its old function

I don’t see the option to change this in the settings and I’d like to have it the way it was before the update

This might as well be a bug because other commands like cmd+z and cmd+opt+a either don’t work at all or only if you press it multiple times

What was the existing behavior?

It used to move the cursor to the far left or right but now it changes the page instead

This has been fixed in one of their updates
