It is easy to imagine an argument for adding all of these.
It is also easy to imagine an argument for having none of these.
Since no criterion for inclusion has been offered, it is difficult
to choose between these arguments.

My personal reason for inquiring about `kbd` (but not about
`samp` or `var`) is purely frequency of use.  I use a `kbd`
role almost as often as a `code` role (and much more often
than `strong`).

I suppose the best general argument turns on the value of a semantic web.
Here the `kbd` tag seems quite valuable in improving webpage accessibility.
But again, I was not motivated by general arguments, but simply
by my personal frequency of use.

Cheers,
Alan
