in the spirit of mobileread, Assuming the terminal is myts
I will post his likely solution.
Useful keys to run gmplay would be:
~ = Menu + q (root home directory)
note: The kindles root accounts home directory is very likely
not where you wish to actually operate from, so think on)
: = BACK + . (possibly useful for specifying ports)
/ = BACK + v
| = BACK + c
- = BACK + f
. = . (duh)
MENU + Z = Tab command Autocompletion
Up on 5 dir controller = Previous Command
Hope that helps.
