Here is the forum thread: https://forums.debian.net/viewtopic.php?t=160926 Relevant quotes: > After putty's upgrade to 0.81-3, I noticed that pgup and pgdn have > stopped working in my ssh session.

This answers some of my questions: - it's all of what PuTTY calls the 'small keypad', not just PgUp/PgDn; - it's not nano-specific (affects bash/readline and less too); - it doesn't look like non-default settings are in play; - it apparently regressed between 0.81-2 and 0.81-3, which the changelog has as very tiny Debian packaging changes that ought to make no difference to this behaviour (...which makes Computer Enthusiast's recompile seem more relevant; undefined behaviour or miscompile or something?) It does seem like this would have to be investigated with the exact 0.81-3 binaries (which I'm not in a position to do).
