Shortcuts to switch between tabs not working on MacOS

[AlbyIanna]

Bug Description:

It's impossible to switch between tabs on MacOS using the keyboard shortcuts. This happens because the relative keybindings overlap with the ones used by the OS to switch between applications.

Steps to Reproduce:

1. Open a workspace with multiple files
2. Ensure you have multiple tabs open
3. try to use the shortcuts ctrlcmd+tab, ctrlcmd+alt+d, ctrlcmd+shift+tab, ctrlcmd+alt+a (as defined here)
4. 🐛 Nothing happens

Expected behavior:

1. Open a workspace with multiple files
2. Ensure you have multiple tabs open
3. try to use the shortcuts ctrlcmd+tab, ctrlcmd+alt+d, ctrlcmd+shift+tab, ctrlcmd+alt+a
4. 😄 Happily switch between tabs without touching your mouse, like a pro

Additional Information

I suggest changing these keybindings from ctrlcmd+... to ctrl+....
