The new Model Coordination Object Table shortcuts are a welcomed addition, but they only work while the Object Table has focus. This means their usefulness is greatly reduced.
The shortcuts should also work while the Viewer window has focus.
I realise that there are some overlaps of shortcuts between the Viewer and Object Table, such as the arrow keys and spacebar.
Lastly, the shortcuts don't even work perfectly when the Object Table has focus, such as when a row's checkbox has been toggled. This means that the Isolate shortcut doesn't work well.
e.g. You select (check on) a row then press 'I' for isolate. Nothing happens. You then have to click somewhere else in the Object Table so that the isolate shortcut works.
P.S. How about some additional shortcuts for 'Restore Previous Visibility', and 'Show All Objects'.
