Are there any good resources on keyboard event handling in Windows Runtime?
I need to to process keyboard events in TextBox controls (and other UI elements) in Windows RT, but have some problems. For example, the KeyDown event handler seems not to be fired in the TextBox when the backspace key is pressed (*CoreWindow::KeyDown fires, though, but that has other problems described below*). 

I've been trying to find good resources on how keyboard event handling is dealt with in Windows RT, but haven't found any but lightweight documentation on the topic (eg. which classes exists etc). Any pointers to samples and other resources on this topic would be greatly appreciated. 

In particular, I'd like to learn how keyboard events are processed in general in Windows RT, to answer questions such as "*Why does my TextBox::KeyDown event fire **before** my CoreWindow::KeyDown event?*".

I'm asking because I am currently porting a multi-platform application, that have an extensive keyboard handling implementation in place. I do not want to re-write this for a single new platform. At the most basic level, the existing code performs filtering on text input in textfields.
