[Geany-Users] Problem with Set Custom Command

[Richard Hardwick]

     I have a problem with
       Edit-> Format-> Send Selection to ->Set Custom Command

     I am trying to sort some lines of text in Geany.
     So I did
       Edit->Format->Send Selection to->Set Custom Command
     and then ->Add

     I got [1.][Tick, or √ sign]
     I typed 'sort' and then ->OK

     The word 'sort' disappeared

     And Edit->Format->Send Selection to says
     "no custom commands defined"

     Same thing happens if I run Geany under sudo
     and whether or not I have selected some text before starting

     What am I doing wrong?
     I am running Geany 0.21 under Ubuntu 12.04
