I realise this is old, and you've already accepted your answer, but I believe that Far 3 comes with the FarCmds
plugin (certainly the nightly build that I just downloaded does).
This allows you to copy the output of commands into the edit or view windows, using the edit:
, view:
and other "commands"... like so:
C:\tmp> edit:< systeminfo
Basically, it's redirecting the command systeminfo
into an instance of the editor. You can even copy directly to the clipboard by using clip:
instead. FarCmds
is one of my most-used plugins.
