Yes, but "process" handles the text "as if it had been typed in from the 
user’s keyboard."  Keep that in mind.

How would you evaluate the contents of the register as screen command doing it 
manually?:
- Press Ctrl+A (or whatever you have you escape key set to)
- Press ":" (colon) key
- Type in: eval 'echo text one' 'sleep 3' 'echo text 2'
- Press Enter

With "process" is the same, just that you use some special notation for some 
keys:

register r "^A:eval 'echo text one' 'sleep 3' 'echo text 2'^M"

The same steps as above:
- ^A  (screen parses this as a Ctrl+A)
- ":" (colon)
- eval 'echo text one' 'sleep 3' 'echo text 2'
- ^M (screen parses this as Enter)

Or you could insert a literal "Ctrl+A" or "Enter" by typing "Ctrl+V , Ctrl+A"  
or "Ctrl+V , Ctrl+A".  That works within vim or bash shell (probably not in a 
gui editor).

Note how these literals are displayed "^A" and "^M". So if you need other 
special keys, you can do the "Ctrl+V , ..." sequence at a bash shell to find 
out how to type that key in screen commands.
