Note: more *is* less on FreeBSD. They are hardlinks to the same binary. The only difference is that more has -X enabled while less doesn't (and a few other niggles, but that's the main one).
This trips me up all the time switching between FreeBSD and Linux, as more on Debian is the ancient, craptastic, real more that does very very very little. And using "less -X" all the time is a pain. And aliasing more to 'less -X' causes more problems when you switch to root or connect to a system where you forget to put the alias.
