How do I hide a non-visual component on a form at design-time?

Question

I am working on the GUI of an older program (in Delphi). Some of the forms are small and have a number of non-visual components on them (UDP servers, UDP clients etc). I'm sure I used to be able to hide/show the non-visual components on the form with a hot-key, but I can't remember what it was. It may have been in an add-in that I have not added-in since upgrading to XE. Does anyone know where/what this might be?

A rather drastic measure would be to upgrade to Delphi 10 Seattle (or later) as this is one of the new features that Embarcadero have added. There is a small button next to "Toggle Form/Unit" called "Show/Hide Non-Visual Components" - the shortcut is CTRL+H
