Problem / Steps to reproduce

Most configuration options are toggleable via --bind syntax. From what I can tell, --pointer doesn't have an option like this. I would personally use this for hinting which mode I'm in (I've used bind to setup a faux-vi-mode, where i and escape toggle whether j and k go up/down or not).

fzf 0.59.0 allows you to toggle the input section (prompt + info) and I think you can use it to implement mode switching.

fzf --layout reverse-list --no-input \
    --bind 'j:down,k:up,/:show-input+unbind(j,k,/)' \
    --bind 'enter,esc,ctrl-c:transform:
      if [[ $FZF_INPUT_STATE = enabled ]]; then
        echo "rebind(j,k,/)+hide-input"
      elif [[ $FZF_KEY = enter ]]; then
        echo accept
      else
        echo abort
      fi
    '

The presence of the input section should be a clear indicator of the mode you're in. Do you still feel the need to change the pointer?
