.zshrc I have
zstyle ':completion:*' menu select=20
This way when I hit Tab twice, I receive a menu of completions (assuming there are at least 20 to choose from). I can then navigate it using Up and Down keys. I would expect PgUp and PgDown to scroll up/down a page, but that is not the default behavior.
A natural idea is to use
bindkey to bind PgUp and PgDown to appropriate commands. However, I can find only
down-line-or-history in the docs, but not their page analogues. What am I missing?
