...this is the method I use and it seems to work fine [I'm running 11/14 21864]:

REASSIGNING THE SOFT KEYS in TouchFlo - Touch Pro Tweek is cooked into this ROM. You can find it in START- TOOLS-TWEEKS-Touch Pro Tweek. I’ve used this application to successfully reassign the left soft key to Camera, but you can choose from a variety of programs and actions. [soft reset to apply changes]. Mapping the right soft key in Manila 2.5 I have not done, since it's dedicated to the "2.5 Home screen Menu".

I have not had luck using Advanced Configuration to perform the key reassignment. Also, the SoftKey Manager program [START-TOOLS-Softkey Manager] will only reassign the soft keys in Titanium, not TouchFlo.
