etaoin shrdlu
February 24, 2023
When typesetting on a Linotype, the operator often made a mistake that was easier to reset the line versus correct the mats (individual character matrices). They would often drag their finger down. the leftmost 2 columns on the keyboard to type “etaoin shrdlu.” This told the person locking up the page to PULL that line (shown in red above) out of the text and close the lines. The line was accidentally not pulled, resulting in the mistake printed above.
Looking at the problem lines, you can see that the characters at the start of both lines are correct. They are just in the wrong order.
You can see by the image below how easy it is to simply drag your finger down those left two rows of keys.
