Although sadly discovered that pause doesn't actually pause stuff fully, just pauses the notifications.
For stuff I want to properly pause I set up a work profile and have things in there that I run infrequently/don't want to give access to my main profile.
Did you know you can use the space bar like a mouse pointer and slide the cursor left and right when inputting text? I found that about 2 weeks ago.
I think all apps have pause as an option but they can also add whatever shortcuts the dev does/doesn't want to in the long hold menu.
