I use ⌘← and ⌘→ to move between tabs. I want to transfer this setting to Safari.
The default Safari keyboard shortcuts shown in the menu bar list ⌘[ and ⌘] for Back/Forward:
Despite those keyboard shortcuts, Safari also seems to use CMD-Left and CMD-Right for Back/Forward.
I can set my desired keyboard shortcuts in System Preferences > Keyboard > Shortcuts:
This now works, partially. If the current tab has no Back/Forward history, the browser will navigate to the next or previous tab.
BUT, if the current tab does have Back/Forward history, my custom keyboard shortcuts do not work. Safari instead uses the default (but not listed in the menu bar) Back/Forward commands.
Why do these secondary keyboard shortcuts exist in Safari? Where can they be customized? How can they be removed?
macOS 10.13.6, Safari 12.0
