since long press home already brings up recent apps, what i did was download "exsbar" from the market, and it allows you to map long press search to any application. i use search a lot in apps like youtube, browser, etc. i personally mapped it to camera, so i can launch it from anywhere in the OS.
seems like recent tasks having to be remapped to the search key seems pointless since long press home already does that by default, and that can't be remapped....
i disagree that it's "pointless". Long-pressing seems to have a delay of 2-3 seconds (for me) before the menu comes up. Simply tapping the capacitive keys is nearly instant. it's nice to have instant access to something i actually use.
wish this were available for euphoria.
