  Summary
    fzf --filter "///" < $DATA | head -30 ran
      1.16 ± 0.03 times faster than fzf-a5447b8 --filter "///" < $DATA | head -30

• Added jump and jump-cancel events that are triggered when leaving jump mode

  # Default behavior
  fzf --bind space:jump
  
  # Same as jump-accept action
  fzf --bind space:jump,jump:accept
  
  # Accept on jump, abort on cancel
  fzf --bind space:jump,jump:accept,jump-cancel:abort
  
  # Change header on jump-cancel
  fzf --bind 'space:change-header(Type jump label)+jump,jump-cancel:change-header:Jump cancelled'

• Added a new environment variable $FZF_KEY exported to the child processes. It's the name of the last key pressed.

  fzf --bind 'space:jump,jump:accept,jump-cancel:transform:[[ $FZF_KEY =~ ctrl-c ]] && echo abort'

• fzf can be built with profiling options. See BUILD.md for more information.
