I can access files in the /usr directory but it's a little odd. For 
example with <Ctrl>O I can navigate to 

/usr/share/arduino/examples/01.Basics/Blink/Blink.ino

After I select the file it opens and the URL bar becomes

file:///run/user/1000/doc/e6a3bfe2/Blink.ino

I can also  

cat /run/user/1000/doc/e6a3bfe2/Blink.ino

to see the contents of the usual Arduino 'hello world' example. 

There is also /run/user/1000/doc/by-app/ which appears to have running 
apps. For example, thonny wasn't in the list until I started it and then 
snap.thonny appeared. 

The entry doesn't go away when I exit thonny, nor does Blink.io when I 
close the Firefox tab. 

/run is relatively new. I've never poked around so I don't know if unused 
data expires at some time.
