Please close if this is a duplicate of #3298, I couldn't really understand the description.

It would be really nice to interactively change the height of the fzf window (e.g., via --bind), rather than hardcoding it via options. The specific use case in mind I have is with --preview using tree, where for deep trees it would be great to toggle how much you can see.

• would that work for you as a verbose workaround ?
  • upon ⌃ Control + A it should open a new fzf process and still have the same selected line, query input, appearances and functionalities, but with a larger height

FZF_DEFAULT_OPTS="$FZF_DEFAULT_OPTS --preview 'tree -C {}' --prompt 'Directories > '" \
    FZF_DEFAULT_COMMAND="fd --type directory" \
    fzf --height '10%' \
        --bind 'ctrl-a:become:pos=$(({n} + 1));fzf --query {q} --height "100%" --bind "load:pos:$pos"'

PS: see man fzf for explanations; {n} starts at zero, thus pos=$(({n} + 1))

Which part of the answer did you not understand? Nothing's changed, and I'll have to repeat it again.
