Hi, @Aravisian just a suggestion.
I think you have let some systemd parlance replace your keyboard key's name.
Normal practice is:
Ctrl+ Shift+ V
Ctrl+ O
Ctrl+ X
[I removed the markdown for O as it makes it squashed like a zero. Perhaps markdown authors/Discourse needs to rectify this?]
I am honestly bewildered as to what you mean, here.
ctl is used in systemd parlance as in systemctl - I sometimes have to correct myself by adding an 'r' by mistake!
Oh... I see it. Eh, you are probably right about systemd being responsible and I think I do that all the time...
I think it is better to use Ctrl+o not Ctrl+O, as lower case "o" avoids any confusion with "0" (zero).
In the past, Computer Science students were told to write numeric zero as Ø to avoid such confusion.
Sorry. I appear to have extended the thread diversion from zRAM subject.
Tis more of a guide(pirate speak) argh argh...lol
Maybe adding a short Foreword with an Explanation what that is with Advantages and Disadvantages could be a good Idea.
Honestly, not even going to deal with this.
Having spent a lot of time with paper and pen I always write zeroes with the forward slash through it as an IT Auditor. This led to a certificate on a course I attended holding my wrong date of bith wit said zero being mistaken for a 1! 
Think how much more fun we would have if Discourse had a green screen with the old fashion terminal characters!
This post got me thinking. If I put keyboard commands in the manual I will be using this font family:
Ah, the Fallout Hacking Mini Game. I really like the Games.
