Use execute(-silent) on all selected lines

[fritzrehde]

Is it possible to use the execute command (which can be mapped to a keybinding) to all currently selected lines?

[junegunn]

Yes, with {+}.

fzf -m --bind 'space:execute:echo {+}; read'

See "PREVIEW" section of the man page.

A placeholder expression starting with + flag will be replaced to the space-separated list of the selected lines (or the current line if no selection was made) individually quoted.
