paola, thanks for answering. I must add that highlighting in the CR is a bit tricky and archaic for touch device. Moreover it will not work without tweaking keymaps.ini file. So I think the preinstalled reader is probably suits better. scende if you still would like to try, please let me know if you need some help with it?
PS:
Here you can find latest CR with some adjustments (by serg_kv @ the-ebook.org forum) for PB Touch models. Note, in order highlighting to work no action should be assigned to the "Home" and "Menu" buttons in the device settings.
