Writes the entry to an fzf#vim#ipc fifo, so it needs the asynchronous fzf#run from junegunn/fzf@5cb7bab7 (junegunn/fzf#4897, 0.74.4), which the g:loaded_fzf check detects. Commands declare '_show' for the entry kind and '_hint' for footer keys, so the footer and the binding cannot disagree. s:can_show withholds both when the run would block, when the window to open in is not visible, or when g:fzf_action, the paste key or the command itself already claims the key. g:fzf_vim.show_key configures the key, empty to turn it off, comma-separated to bind several ('ctrl-o,double-click'). Named for its 'Show' footer label, since Enter already occupies 'Open' there. Only the first key is labelled, and a clash on any of them drops all of them, so the footer cannot list a key that does nothing. Binding Enter drops its 'Open' hint too, since fzf accepts on Enter rather than through g:fzf_action. s:show_entry parses each entry the way that command's sink does and runs win_execute() in the window fzf started from. That keeps the focus in fzf and works from a popup, which win_gotoid() cannot leave. It opens with 'keepalt keepjumps hide', so stepping through entries leaves the alternate file and the jumplist unchanged. BLines, BTags and a lowercase mark carry a position but no buffer, so the callback carries the buffer the run started on as well as the window. fzf#run is asynchronous, so runs can overlap, and a second run would stop the first's ipc channel and overwrite the script locals its sink reads back afterwards. Channels are now keyed by fifo path and per-run state is bound into the callback instead, which is why Buffers, Colors, Jumps, Maps, Helptags and complete change here.
