How to disable back and menu buttons for certain apps

[AC Question]

I have a problem where i am reading someting on the internet or other places i sometimes touch the back button and have to search for where i was.

I don't believe you can without root access. Even then you may not be able to have them disabled for only a few apps.

Is there an app that can run in the background and disables the back and menu button while that app is running in the background?
