I forgot to mention that it's on SW 2015. Otherwise, the Shift+Tab is not quite what I'm looking for because you have to go through a bit of a vacuum to display the components.
The "Show hidden components" command displays the hidden components and then you can click on each component you want to re-display, so a slightly different concept from Shift+Tab I think.
Actually that's what I want to do, I would like to assign my own shortcut (Ctrl+Shift+S), but the problem is that the command is not found in SW, so I can't assign a shortcut.
I went to take a look at Customize --> Keyboard. But the command doesn't appear there, so I can't assign a shortcut ...
You're right, this command that corresponds to the icon present in the assembly bar of the command manager is strangely absent from the list to add a patch.
In 2015, the only solution is to use this icon.
If you go to 2016, the ideal remains the solution proposed by @max59
