Extra button options for the TV Button and Home Button?

[dude98]

I use steam, and it has the Home/Guide button combos, where you need to hold the home button down, then press another button. you can't do those on the wii u, because holding the button down closes the stream, and it only sends the input after you let go. I want t have an option to make the home button NOT stop the stream and send normal home/guide button inputs, but that will mean either moving the stop stream button somewhere else, or making you need to power the wii u off to stop streaming. Also, i'd like to be able to open a keyboard you can type into using your stylus for stuff like messaging people or searching things on the gamepad. i have no idea what the TV button does, so i wanted to suggest this if possible, if it's not, steam has an on screen keyboard i can use, but the letters aren't very big on the gamepad screen so it's slightly hard to see.
