comparison termemu-keys.js @ 70:d7eb63cd7a16

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Try to get some compatibility for keys. I'd thought using the DOM_VK_ names was a good idea. Symbolic names ought to be more portable than opaque numeric constants. Foolish me, expecting things to be sane. Keys now work with FF15 and Chrome 17.
