This is a change in macOS Monterey when you are using a non-US keyboard. For AppKit-based apps it automatically remaps many keyboard shortcuts based on the physical layout of keys. Therefore you should see this behaviour in many apps. Developers can opt out of this if they’ve already localised all their keyboard shortcuts, but this was rarely the case.
In the past many keyboard shortcuts which were not based on alphabetical letters were awkward to press or impossible to reach on localised keyboards, because they were chosen by app developers based on the physical layout of keys on a US keyboard, and not localised.
A good example is the
] keys to the left of the
Enter key on a US keyboard. On many keyboards (eg. French, German, …) those characters are accessed using one or even two modifier keys. This meant that in OmniFocus you could trigger the ‘Add Inside
Shift-Cmd-]’ and ‘Add Outside
Shift-Cmd-[’, but not the ‘Indent
Cmd-]’ or ‘Outdent
Cmd-[’ shortcuts (because you already had to press
Shift-Option to access the bracket characters!). In Monterey you press the same physical keys as on a US keyboard without any additional modifier keys. Same thing for all shortcuts which are based on the row of number keys on a US layout.
This change will require relearning some muscle memory, but I think keyboard shortcuts will be much more useful and intuitive once you do. You also have the option of remapping the keyboard shortcut of any menu command in macOS System Preferences.
