Default [Q] Disable Buttons

Hi all

I am wondering about something. Is There a way to disable the onscreen buttons, when the keyboard is open? But now can the main question is can the back button be left enabled so you can close the keyboard. I find that I am constantly hitting the home button when using the keyboard, and would love to have that disabled while the keyboard is open.

Thanks to any help.

Regards
