Thank you geekmaster. Sumarizing: I'm trying to make pageturn work so tried "waitforkey" in the kindle's search bar (missundertood you) Then, when trying to access debug mode, I was unable with `debugOn but could enter with ;debugOn (separate question...) In fact it's a long time since I don't use debugOn so probably it has worked always with ;debugOn not `debugOn and I used ` to run commands. Ok, all this is a different vortex I got into so let's forget it :-)
Once I was able to run waitforkey using ssh, the key codes I got were not the same you can see in myts (althought they are the same as launchpad) so I spent some more time trying to guess what happened. In the end I remembered I'd to add something else to myts' keydefs.ini to make DXG work. Second vortex. Survived too...
Present situation: pageturn doesn't yet work; it creates "key" (empty) file in /tmp when pressing the mapped key but does nothing.
I'm sorry for disturbing you, they all are problems related with my absolute and deep ignorance... I hope you (and the rest of the members) will forgive me for being so a pain in the ***
Regads and "Long live and prosperity"
