Can you change what menu buttons are on the bottom of a screen say like your email screen. Right now I can replay, new and scroll up and down. Say I wanted one of the menu buttons to be keyboard instead of replay. ( just for description sake) Can you change those? The one I really want to change is when I am reading a thread on a forum instead of the www. one at the lower right corner I want to just pop up my keys and not have to hit BBmenu and then show keys.
