Comment 4 for bug 912531

Well, we can define our own `vm-w3m-minor-mode-map' and dump the standard one. That is what should have been done originally. (But, Katsumi Yamaoka was probably not much of a VM user, and he just produced a sample interface that we could build on.)

In this minor-mode, we can rebind "[" and "]" to w3m-previous-anchor and w3m-next-anchor. We could also bind "C-x [" and "C-x ]" to the image navigation functions. (I don't think anybody would need "page" navigation functions in an email message.)

We would also need define a context-menu (mouse-3 menu) that can be used on URL's which should look the same as in normal VM mode.
