Keyboard Input Issues

Hey folks, first I want to say how much I love this project. Great concept and this is almost usable as my everyday shell. But I'm having some issues that I can't get past.

1. Ctrl-w closes my shell - This is something that I can't get past. Ctrl-w in bash should kill the word before the cursor.

2. Ctrl-d doesn't act as Del key - Another bash-ism, if there is text present then ctrl-d should act as if Del were pressed and delete the character in front of the cursor.

3. Various things break in Emacs - Mouse scrolling & ctrl-arrow keys don't work. And Page Up/Page Down will actually print PageUp or PageDown when pressed.

        "log"                                                                                                                                                                                        
        "net"                                                                                                                                                                                        
)PageDownPageDownPageDown                                                                                                                                                                            

It also seems like Emacs can't tell how many rows my shell has. Text at the bottom of a document is unreachable.
