And what sequence am I supposed to use with regard to specific `$OSTYPE`? The sequences, as I understand, are bound to a particular terminal emulator, not necessarily OS. What I _can_ do is apply `\eOc` and `\eOd` conditionally only if `$TERM=*rxvt*`, like Debian does. The other codes apply for xterm, it seems, and anything else is beyond my understanding.
