Global vs Workspace controls split can feel confusing

Describe the bug
My first action when testing keyboard controls was to open the hints, and start trying to use them; however, when you do that, only a few work. I first wanted to click L to try and download to see an immediate response, but nothing happened; then i tried w to select the workspace, but that also does not work. It sounds like current intention is ctrl+B -> 4 in that scenario to get back, but 'get back to my code' feels like a common action and that's a fairly dense interactoin.

To Reproduce
Steps to reproduce the behavior:

1. Go to blocks editor in narrator mode
2. control+/ to see keyboard shortcuts
3. try to do one of the actions in blocks workspace, because those are the ones that 'feel' most likely to want to be used / take up most of the screen
4. See error, the button event is captured in the iframe and does not do anything

Reproduce this in the blocks editor using narrator mode: open keyboard shortcuts with Control+/ and try the listed actions inside the blocks workspace. Start by tracing the keyboard shortcut and iframe button-event handling around that workspace. Done means the relevant shortcuts produce their documented actions there, or the controls clearly indicate their scope.
