How do I switch tabs when using iTerm2 with Z shell
Solution 1:
Use the keyboard shortcuts Shift + Command + ] and Shift + Command + [ to switch to next and previous tabs respectively. The same are also available under iTerm2 Menu Bar → Window menu.
The keyboard shortcuts remain the same irrespective of the shell you are running.
Solution 2:
You can view/update current key bindings if you open the Preference window from the menu bar iTerm2 > Preferences > Keys > Key Bindings
For me, command+←/→ as well as command+shift+[/] (as mentioned by previous answer) work by default.
I am using iTerm2 (3.3.7) on macOS Catalina (10.15.2)
Solution 3:
On the trackpad: two-finger swipe, left and right will scroll through the tabs.
On the keyboard:
Shift + Command + [ (scroll left)
Shift + Command + ] (scroll right)
The keyboard commands loop through tabs, whereas the trackpad gesture does not.
