Add Keys as an "other instrument" topic

I've been using Chordie for years and have modified  hundreds of songs for keyboards.  I don't know why others don't talk about using chordie for playing keyboards. 

Any chance of adding Keys under the "other instruments" topic to see what kind of response you get from  readers on using chordie in songbook or other apps for keys?  I have come across a system for writing tabs in chordpro format for use on keyboards.  I'd also be willing to help try to get keyboard users involved in using chordie.
