I see that it is now possible to upload custom remote files for the slingbox 350. I am trying to control my SKY+ box located in the UK attached to a Slingbox 350. I have no problem with a mouse and keyboard, but I am now trying to use a Harmony 650 emulating a Window MCE keyboard controlling a IR receiver (from a Rosewill MCE remote). I can send single keyboard shortcuts but I am unable to send combos e.g. ctrl + shift + r for the red button. It would be great to be able to assign keyboard shortcuts to unused letters on the keyboard rather than combinations. However, I have no idea where to even start!
