Frodo

, or anyone else that might know :
I'm using an IR remote control to send keyboard commands to FP. Using the touchscreen while driving is too difficult.
Most of the keyboard automation commands I need are there, except that I'm having a bit of a problem with the DirListing commands:
w dirlist down
q dirlist up
e dirlist select
a dirlist left
s dirlist right
I use this mode 99% of the time. While I can go up and down in the directory hierarchy, I cannot expand a folder if it has subdirectories using the keys above. FP requires a double click at that location to expand the subdirectories. How can I assign a keyboard shortcut to expand out a directory's subdirectories?
Thanks.
