not all rox filers are set up to allow right click function activation by letter (they all seem to be able to do the speed dial by number part though). to enable the function in p6 or any other pup that doesn't seem to be able to set letters for the right click options, enter the following into a terminal (will restart x):regarding rox, there is probably no faster way to navigate folders or create files than rox with short cuts set. right click to go to the create new file dialog and press a letter--now every time you are in a rox folder and press that letter, a copy of that document type will appear for you to retitle/save as in that location. ctrl+1-0 gives you speed dials to ten locations, ctrl+b is book marks (you can short cut open parent in new window to get a freebie bookmark/dual plane set up. you could also make a bookmark of a folder of symlinks to launchers, files, programs, directories, etc).
sed -i '1 i\gtk-can-change-accels = 1' /root/.gtkrc.mine; restartwm
if the terminal responds that the file doesn't exist, enter touch /root/.gtkrc.mine and rerun the previous command(s). delete the semicolon and restart command if you want the function ready to go but aren't in any particular mood to restart x.
