Workbench claims wrong shortcut will launch GTK inspector

[ferdnyc]

The Platform Tools module found in the Library says, at the bottom of its rendered output:

As with most GTK applications, you can use the keyboard shortcut
to open the Inspector and select an object to see what it is made of.

Ctrl+Shift+I

Except... Ctrl+Shift+I doesn't open the inspector. On my Fedora 36 system, at least, a Ctrl+Shift+I in Nautilus (for example) results in a "Select All" being performed in the focused window.

Ctrl+Shift+D launches the GTK Inspector.

Edit: (In fact, Ctrl+Shift+I doesn't even open the inspector in Workbench. Even there, the only working shortcut AFAICT is Ctrl+Shift+D.)

Yeah it's a bit tricky.

Ctrl+Shift+I is to open the inspector with the element under the cursor selected. It works for me, but there might be certain states where it doesn't.

Ctrl+Shift+D is to open the inspector without anything selected. I have found this shortcut not to work reliably – here I have to activate it twice (or Ctrl+Shift+D then release D and press it again).

That's why I chose I over D. I guess that was probably a workaround.

Do you also have to press Ctrl+Shift+D twice?

@sonnyp

Do you also have to press Ctrl+Shift+D twice?

Yes, but only if:

1. I've already had the inspector open
2. I closed it using the titlebar close button, rather than by hitting Ctrl+Shift+D again.

It appears that, when the inspector is opened using Ctrl+Shift+D, the Ctrl+Shift+D shortcut in the application becomes "Close inspector", and remains that way if the inspector is closed via some other means.

That seems like a Gtk bug that should be reported, to me.

In the meantime, Ctrl+Shift+I is suddenly working for me, when I swear it was not working at all the other day when I tried it. So, I guess it makes sense to document that one instead. (I just wish I could figure out the exact pathology for those times when it doesn't work.)

Thanks.

Agree - would you be able to do so and link it here?

@sonnyp Done! I had to find a second affected app, first, to confirm. But I finally did, with the nightly builds of Nautilus.
