I have a Nexus Player running Kodi and thanks to this post - http://www.reddit.com/r/AndroidTV/comments/2ll0hi/if_anyone_is_looking_for_a_usb_ir_receiver_for/ I purchased an IR receiver with remote and I have programmed the Harmony as a ChinaVasion CVSB-983. All works very well, however the Right Click option, is always based on the centre of the screen so useless to bring up the Menu to allow you to Manage items, and thus remove a show from the library. You can use the mouse controller on the basic remote, and even set mouse controls to the Harmony, but I don't want to use a separate remote, and using the assigning and using the mouse direction buttons is not only annoyingly slow, but 100% not wife friendly. Apparently the "C" button on a keyboard also bring up this contextual menu to allow you to Manage - Remove form library. I added a MCE keyboard as a device in the Harmony, and assigned the C hey to my Guide button, but it doesn't have any response at all. Has anyone figured out a way to delete items from the library with a Harmony remote? Is a Flirc my only option?

Set as your default keyboard. and see if your IR shows up on the list of devices.
I use a flirc, but it may show up, and you might be able to remap a key to 'c'.
