	So, yet another man page; thanks for the datapoint.

	A BEL-per-key drove me beyond the limits back in '99; that isn't
	the answer, but to key a truncated bell, a click, at something well
	below middle-C: yes, this kind of thing is what I'm thinking of.
	What is ed's full email ed[at] where.org, please.

	If he'll give me the clues, I'll share in the hacking.  It is time
	to get this feature builtin to the kernel.  Off by default, and on 
	at some user-tuneable values.  

	If only 1 peraon in 10K uses it, that's fine.  For me, it makes
	typing do-able.

	Well, as a last-resort kind of solution.  I think it's time to get
	at this by hacking the driver.  But since it has been so long since
	my last go, some/any help would be much appreciated.
