[GreenKeys] Touch screen green keys?

[steve bennett]

GKs,
  Before I reinvent the wheel I thought I'd reach out and ask if anyone has already done this.Since my M15 is read only (no keyboard) I was thinking of using an old tablet or Android as a virtual keyboard.For simplicity I was thinking of implementing this in some sort of client side mobile code like  javascriptand HTML. Say for example take an image of a vintage green keyboard and slice it up into javascript buttons.The idea is when you touch (or click) a button it triggers an audio sample of the AFSK for that characterand the sound output of your device is plugged into your TU.(Yes I know I could use FLDIGI but I want to use a graphic key board with green keys)
As a proof of concept I have already generated the necessary audio files and tested it with my android phone.On the Android plugged into a TU170 if I play A.WAV the machine prints an A, so on and so forth......Works great but it is tedious to scroll through a list of audio files to find the letter you are looking for.
Any thoughts?Surely there is HTML and Javascript already out there somewhere that just needs adapted to this purpose.A keyboard input being such a universal and fundamental widget there has to be one out there I could just download.No need to write it from scratch.
