Can you change what menu buttons on ....

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.

Thanks.

No current option to do so.
You know though, you can just swipe up and your keyboard will be displayed.

Very cool did not know that, thanks.
