KBD2 test in HP48SX

[supernumero]

Hi,

I was playing with my 48SX. After running the "standard" keyboard test KBD1 by ON+D then E, I discovered that ON+D followed by F launches a test called KBD2. But, I don't know what it does. I haven't been able to find this documented (this is not in the manual, and Google did not help). Does anyone here know?

(I did not try this on my 48G, which is in my office at work.)

PS: I found some info on KBD2 test for the 49G:
