It seems like there are only, an isolate and hide/show a single collection, hotkeys, but no show all collections hotkey. Am I missing something?

I often accidentally isolate a collection and it's a bit awkward, that you have to press undo, instead of clicking 1 twice for example.

Put the mouse cursor over the Collections field and press Alt+H to unhide everything.

  • $\begingroup$ Don't. I struggled a bit to find it too. However if you have a lot of hidden objects in your scene you don't want to unhide everytime the workaround hatinacat2000 suggested is a better way to go. $\endgroup$

Workaround: Make 1 new collection at the top; Drag-drop all other collections into top collection.


I'm here because I had the same issue. I kept accidentally hiding the collections (bar the first) by pressing 1.
Intuitively I pressed 1 again to reverse the situation. An easy mistake, but an easy fix, I thought.
Here I find out that I need to drag my cursor over to the Outliner, then press Alt+H to reverse the mistake.
I appreciate that people have supplied the answer, but I feel Elmazz makes a good point: Please make 1 a toggle.
