In kde 3, krunner (equivalent of xfrun) had 2 very cool shortcuts: #prog launches man-reader on page "prog" (ie konqueror man:/prog) ##prog lanches info reader on page "prog" (ie konqueror info:/prog) As these shortcuts beginning by '#' cannot be used in command-line i guess the risk of mistakes is rather low
Fixed in git master, man pages are opened in the default terminal emulator.
