A lot of us still remember the typewriter. But what key was found on most, yet is not found on the keyboard of any computer?
And on some typewriters, one key was double-duty. What did that one key equate to?

No thoughts yet?
That "special" key on most typewriters had a "1/2" marking on it. When typing, if you missed a character, press and hold that key and then the missing character key. Better than all the retyping.
As to the double-duty key, some typewriters did not have a "1" numeral key. The lower-case "L" key substituted for it.

Here is a forgotten term for some, relating to automotive use.. "crash box".
Anyone remember?
How about "double clutching"?

A "crash box" refers to the gears in a manual transmission that do not have a synchro mesh feature. Takes skill and practice to shift one, without 'grinding' some gear burger!
The term "double-clutching" also applies to a "crash box". When down shifting, you put the trans in neutral, let out the clutch, and rev the engine a bit. Then shift to a lower gear.
Thankfully, almost all manual transmissions today have a synchro mesh design on all gears except reverse.

Here is a term used in older TV sets.. "time pipe" or delay line. Anyone know what it is and does?

Older analog TV standards did not have enough bandwidth to carry all three color spectrum info, plus video and matrix audio.
So a 360° "pie" was created of the three basic colors. Two color spectrum info signals were sent, and the sum difference was created in the TV circuit. The two sent signals were carried in a "time pipe" or delay line, and all three signals merged at the proper instant for a complete image scan.
Oldest models had a paper tube, about 1/2" diameter and about 6" long, wound with fine wire as the delay line. Newer models used a synthesizer that was offset by a few microseconds.

Here is an oldie..
There once was a "miner's tea" that was renamed and is a popular "bubbly" today.
Who first made it? What was the original use for it?
