This isn’t only good for commodity but also accessibility. People with certain mobility issues might find it hard to work with a mouse and would have an easier time navigating everything with keyboard shortcuts.
Unfortunately there’s not a single or simple fix here to get universal keyboard navigation in all windows. But we have been keeping keyboard nav in mind as we are working on the new UI systems and Studio architecture. We also have a Shortcuts overhaul on the later part of the 2024 roadmap where we should be able to make some progress in this area.
