Re: buffer list

Instead of using a dialog, what about some sort popup, like used for
name completion? Is it possible to use something like that to instead
popup a buffer selection list?

Also, regarding keyboard usage, can the key handler detect events on a
fine-grained-enough level to act on key-up and -down? Eg, if I wanted
to popup something and simulate alt-tab-like behavior where I can hold
the alt key down press or release the tab key, and the selector list
stays visible until I release the alt too.
