remapping buttons for list scrolling (ipod video)?

(1/1)

peterw:
I'd like to remap Hold Prev and Hold Next so they can be used to scroll through long lists, as when browsing the database. I hoped this might be as simple as the following patch, but apparently it's not. Could someone help me figure this out?

Thanks,

-Peter

OK, bad form, replying to my own post. I got it figured out, and posted a patch on Flyspray:

Llorean:
Wouldn't a better solution be improving the scroll acceleration code, so that holding left and right can be used to scroll long filenames manually as can be done on other targets?

tdtooke:
There is another patch with addresses this that you may be interested in.  You have an added scroll-acceleration setting for fast, faster, fastest which you can set to whatever suits you.

Thank you. I think that will become abother "core patch" in my build -- that makes the wheel much more usable!
