Thanks for the update for the K3. I will check it out and let you know if it works for me on my Keyboard 3G US.
Edit: Opening pdfs via highlighting them and running a Launchpad shortcut to kpdfviewer seems to work for me. However, doing the same thing in CoolReader (which uses a 'goqt.sh' file just like FBReader (which I altered), and a similar Launchpad shortcut), doesn't seem to work. IDK if its because I am using CoolReader or because it just doesn't work. I don't have FBReader to test this.
Fyi, here is my .ini:
coolreader.ini
Code:
[Actions]
; CoolReader
C R = !/mnt/us/cr3/goqt.sh cr3 "`/mnt/us/launchpad/lhack /mnt/us/documents *.epub 0.6`" &
