The new feature, that enables us to use two part shortcuts, is a really great enhancement. At the moment, when pushing
the first key (for example "o"), the small info at the bottom left shows something like "Alt + O, ...?", to indicate, that another
key is expected to execute the shortcut.
I think, it would make sense to have an option, which flashes an overlay, similar to that of the new copy arrow symbol,
in an unintrusive, semi-transparent way, giving us a list of available options, for about 3-5 seconds. That way we would have a summary
of those options, making it easier to learn or use the various multi shortcuts. After a while the user could probably deactivate the option
in the preferences, reverting to the simplified behavior, that we have now.
