Oh, I’ve been doing the two keys in the wrong order thing such a lot lately!
It’s particularly frustrating, as I’m doing some online language learning, and I confidently type the “correct” answer, and hit return before reading it back - only to find it had a typo in it. So that word (which I knew) is marked wrong, and will be flagged for review again tomorrow - on top of those words I genuinely got wrong.
I know it’s a case of more haste less speed, and if I took the time to read back what I’d typed, instead of what I think I’ve typed, it would happen less often.
But sometimes I’m presented with a couple of hundred words and phrases for review, so naturally I want to work through them as quickly as possible, and press on with the new material.
It’s so annoying when a word I had right in my head goes in the “still not learnt” queue, because of a stupid typo.
One of the two websites I’m using has a limited amount of artificial intelligence for typo detection, so sometimes it will say: “Oops - nearly right - you made a typo!” - and treat the word as correct anyway. But not always. The other site does not make any allowance for probable “finger trouble” and assumes you just don’t know.
