Feature

Is your feature request related to a problem? Please describe.

Add an option to use the Esc key to close the wingpanel after clicking on it and return to previous window. For example, if I have Files open and I click on the WiFi (Network settings), the focus shifts to WiFi settings of course and then we should be able to use Esc key to close that and return focus to Files.

Describe the solution you'd like

Add Esc key functionality to return focus to previously opened window

Interestingly this works in the date/time indicator and applications menu, so I wonder if it's up to each indicator? It makes sense to me that it would be managed by wingpanel itself, though.

Another thing I noticed is that when the cursor hovers over the Applications menu, it shows a preview which says "Applications" but doesn't do that when it hovers over the Date/TIme indicator or any of the ones on the top right. This is of course a separate issue and I'll probably raise a new one but might be relevant here.

@vikasnataraja that's entirely unrelated, but feel free to open issues on the individual indicators to add tooltips.
