As I understand it, it's there because CSI is not a CSI-prefixed
sequence (i.e., you have to first document CSI itself, and then in a
different list you can document sequences prefixed by CSI).
So I'd say it belongs there.

Regarding this, I don't know what the intention of the original author was.

The pre-git code was (man-pages-1.70):

```
ESC ( U \0\0\0Select null mapping \- straight to character ROM
ESC ( K \0\0\0Select user mapping \- the map that is loaded by
\0\0\0the utility \fBmapscrn\fP(8).
ESC ) Start sequence defining G1
(followed by one of B, 0, U, K, as above).
ESC > DECPNM Set numeric keypad mode
ESC = DECPAM Set application keypad mode
ESC ] OSC (Should be: Operating system command)
ESC ] P \fInrrggbb\fP: set palette, with parameter
given in 7 hexadecimal digits after the final P :-(.
Here \fIn\fP is the color (0-15), and \fIrrggbb\fP indicates
the red/green/blue values (0-255).
ESC ] R: reset palette
.TE
.SS "ECMA-48 CSI sequences"
```

Maybe it should go into a separate subsection called "Operating system
commands"?


Thanks,

Alex
