Mouse wheel zoom options and keyboard bindings

[wunderbier]

Two hopefully quick questions:

1) Is it possible to change the mouse wheel zoom key combinations? With simultaneous zoom disabled in track view ALT+MouseWheel is vertical zoom and CTRL+ALT+MW is horizontal. Can I swap these?

2) In the picture attached, why is the list of keyboard bindings so sparsely populated? Many of those functions have keybindings. I can use Locate Key and find the ones I know. But if I want to assign a new binding and I'm unsure if there is already a valid binding I either have to a) open the user guide and search the listed bindings and then find a suitable key combo if there isn't or b) try to guess what the key binding might be with Locate Key and see if it's in use. What am I missing?

2) I've seen this too - I think there is a bug regarding initializing this dialog with populated bindings.

After doing some stuff, don't remember what, you suddenly have it populated.

If searching for a key and assigning something, not sure what it was.
