from the wiki article on QWERTY:
The QWERTY arrangement solved the jamming problem not by forcing typists to slow down, but by separating common sequences of letters in English. Pairs of keys that are frequently struck in succession were placed as far from each other as possible, so that the hammers that were likely to be used in quick succession were less likely to interfere with each other.

one of my friend who is professional secretary, finds on keyboard vs typewriters, (even electron typewriters)she can type faster.
her top speed on a typewriting is about 90wpm, on keyboard typing tests, (for job interview) she has hit 108wpm!
with out any mechanical systems, she can do it faster.
--me? i am lucky if i type 40wpm!

Fal: '"This is spam" button saves you from seeing more spam of the same type,...'
***Forgive if I wasn't clear. I don't think it's even feasible to write an algorithm that can reliably distinguish spam, as compared with the human mind which can do so within a second. It is the subsequent five seconds of his life that are wasted
Certainly the human mind can (but isn't always) much better than any algorithm but there are some pretty good spam filters out there. We have one on our email service where I work that cut my spam load from about 50-100 a day before we went to the service to no more than 5 after we went to it.

Really! If it's no trouble, and if possible, can you briefly explain how it works as I'm sure others of us would be equally interested--thanks--Dale

How it works? Pretty good, I'd say.

Fal: Sorry my q wasn't clear as so often happens. What I meant was, how does the algorithm distinguish between the characteristics of a spam and those of other communiques without inadvertently deleting an occasional instance of the latter

I believe the operation is much simpler than you surmized.
Pressing the "This is Spam" button:
1. moves the currently selected message to the Anti-Virus Quarantine
2. records the sender in order to 'capture' future messages automatically
There is no magic. And I would offer, to the original comment about the time it takes when you "press the button". That is an investment. Every future message, from that sender, will be automatically removed. Consider the time as 'training' your software.

Parkin: 1. moves the currently selected message to the Anti-Virus Quarantine
***Sorry for once again not being clear. I realize that's what happens to it, but my complaint involves the duration of the move
2. records the sender in order to 'capture' future messages automatically
***I wasn't aware of that and thanks for the tip. However, that feature doesn't do much good because with 99.9 per cent of spam the sender changes at each transmission

It doesn't. They're called false positives. Hopefully it doesn't delete the messages that it has identified as spam, but puts them in a folder that you can go through regularly. You can then let the email handler know that a specific message is not spam.

Fal: Thank you once again for the clarification. However, the principal advantage of the spam folder is precisely that you can delete the entire contents of the folder without having to browse the listing
Nonetheless I very much appreciate your help in these matters
