Seriously though, there is a hell of a lot to this thing and pretty much zero documentation. You can actually view the code that gets locally cached in /sys. It is possible to edit the system's code, but you need to have root permissions to do that.
The easiest way to get biofeedback from the bare desktop is to add the hotkey_apps parameter to the url like this:
Then you just press Ctrl+Alt+[1-9], where the number depends on the position in the list of apps, so Ctrl+Alt+1 opens the TextEdit app, etc. You can save files in TextEdit with Alt+s. The desktop currently uses the /tmp folder. You can always pop open a terminal with Alt+t.
I just came up with that name a couple days ago. Didn't check what alternative meanings it might have. I've been hacking on it since 2012. This project has gone by more than one name in the past. I easily get bored of staring at the same old name after awhile.
Even though the obscene meaning shows up at the top of search results, it is not a common idiom, and the rest of the search pages do not reflect the obscene meaning.
However, this HN page does show up in the fifth page of search results, so maybe we can take the opportunity, right here and right now to change the main meaning to a more useful, less obscene one :) !
To make that happen, I created something that I like to call Yabbos: Yet another browser-based operating system.

It has also gone by another name with a reference to Linux, but I got bored of that name after a couple of years of staring at it.
