What issue are you seeing?

While I was entering instructions, I tried to press Ctrl+A to delete the text and rewrite it, but I accidentally pressed Shift as well, so Ctrl+Shift+A was entered.
Suddenly the thread disappeared and a new chat screen opened, which was pretty alarming.

In the GUI, archiving a thread requires an additional confirmation step, but in the keyboard shortcut scenario it just disappeared immediately, which was the first thing that caught me off guard.

Then, because I didn’t want to run into this issue again, I opened the keyboard shortcuts screen, only to find there was no option to disable or remap the shortcut, which was the second thing that surprised me.
