It took me some time but here it is!
Hi @RyanF
Did you have time to have a look?
I just saw new versions of Ghost 5.62.0 has been released (mine is 5.59.2), is there any chance a fix is in it?
Thanks !
Hey! Thank you for the recording, but I wasn’t able to replicate the issue 
I would try updating and see if the issue persists.
If possible, see if you can replicate on another device.
If you’re still having issues, please make a new post on the Forum, explaning the issue.
Just a quick note: I figured out that if the top element in your “select all” selection is itself a snippet, you do not get the full toolbar with the “create a snippet” button.
I worked around it by putting some throwaway text above the top snippet, then was able to select-all and made a snippet that it a collection of snippets.
Hi @RyanF
One year after the trouble I had about the snippet, I just solved the issue.
The main problem was the keyboard layout.
On AZERTY keyboard, the shortcut Ctrl+Q is binded to Ctrl+A which prevent using the “Select all” classic shortcut.
Ex : When I try to “select all” with the keyboard shortcut on a text element, it toggles it to quote Level 1 and level 2 if I try again.
As soon as I switch my keyboard layout to QWERTY, the keyboard shortcut works perfectly and I am totally able to select all and create a snippet from it.
Although, I agree with @BruceInLouisville, I need to have a text element as first element to see the toolbar appear. If the first element is a HTML element, it does not appear.
