  55    %f  The current file (if non-local vfs, file will be copied locally and

  57    %p  The current file
  58    %d  The current working directory
  59    %s  "Selected files"; the tagged files if any, otherwise the current file
  60    %t  Tagged files
  61    %u  Tagged files (and they are untagged on return from expand_format)
  62    %view Runs the commands and pipes standard output to the view command.
  63        If %view is immediately followed by '{', recognize keywords
  64        ascii, hex, nroff and unform
  65
  66    If the format letter is in uppercase, it refers to the other panel.
  67
  68    With a number followed the % character you can turn quoting on (default)
  69    and off. For example:
  70        %f    quote expanded macro
  71        %1f   ditto
  72        %0f   don't quote expanded macro
