I use a ziploc bag and use the commands from
this thread to turn off the screensaver on the Kindle.
At home screen press Del and Sym at the same time and then type:
;debug on
Press Enter
Press Del and Sym at the same time and then type:
~disableScreensaver
Press Enter.
When you want to enable the screensaver press Del and Sym at the same time and then type:
~resumeScreensaver
Press Enter
It works quite well but the biggest issue are poorly formatted cookbooks.
