[AC Question]

I know how to customize the M9's onscreen navigation bar through the personalization settings. But what I can't seem to figure out is how to move (or remove) the "choose input" button that pops up on there whenever I open the keyboard. It sits right where the base of my thumb is when I text one-handed, thus I'll be typing and all of the sudden there is an annoying little window on my screen asking if I want to change keyboards.
