When a serious sort of middle manager I sometimes found I’d left out the odd unimportant little word… like “not”!
And when I worked with someone called Louise, some evil gremlin had me type it as “Lousie”.
“Caught by ARAT in a trap.”
Sometimes I don’t let up the shift key fast enough and I end up with two uppercase letters at the beginning of a word. And sometimes my fingers are on autopilot and they don’t type the word I want. So I try to proof everything before I post - I don’t always succeed, but mostly, I catch the dumb stuff.
Isn’t that a Smashing Pumpkins song?
Mine is udpate for update.
We’re in the most awful month of the year; Janaury!
I’m guilty of this quite often, as well. YEs, I am.
Auto-correct causes me to use “ducking” frequently.
When typing fast, my most frequent need to go back and fix is finishing a word with -tion.
Most of the time it comes out as -toin.
Flase for false, when using Excel, all the time.
Ration for ratio, which is annoying because they are both words.
Acocunt for account, which is a dangerous typo at work.
Those are easily by most frequent typos.
Thanks usually comes out as - thansk
At work, every.single.day I make a report about yesterday’s sales. I’ve been doing this for 20+ years and for the entirety of those 20+ years I almost always write “Monday” instead of whatever day yesterday actually was. I do it often enough that as soon as I’m halfway through the word, my brain automatically checks to see what I’m writing and fixes it if need be. It’s almost automatic at this point.
On a PC with a proper keyboard, my most common is typing the “remember” as “rememeber”.
As to texting on a smartphone, If I had a dollar for every time I tapped “thete” for “there”…
Being a glorified editor, my characteristic typos tend to be limited to adding extra letters at the end of words (e.g.: turning “brew” into “brewer”) or leaving out words entirely.
Speaking, however – I used to have a Tank McNamara problem with saying “check cashed”.
I seem to have a slight problem with “near phonemes”. Things like:
“Was” instead of “once” – seems very weird to me, not a “mechanical” problem but actual crossed wires in my head.
“Though” instead of “thought” – may be just a missed letter, but it happens at least much more with these specific words than any others.
These happen without using any autocomplete or spell check. English isn’t my first language.
On the phone: “enbay” instead of “ebay”.
‘I’m glad the dealie is back up and running. Please let em know if I can offer further support.’
Stuff like that inexplicably happens to me as well, when I’m just in full free-flow typing mode. I usually don’t catch after I post it, but it is really weird how that happens.
It feels like this is a demonstration of how humans process language. The sound takes priority, so sometimes the wrong letters come out when going too fast.
Another type of typo I just made: missing out complete words. I’ve seen this happen with other people too, where the missing words seem typically be of a certain kind, I think I’ve seen it happen a lot with any form* of the verb ‘to be’. Or maybe any verb, not sure.
And just did another one I don’t think is a typical one for me though: apparently couldn’t choose between ‘verb’ and ‘word’, typed ‘worb’.
*) EDIT: ‘form’, not ‘for’ 
I do “thansk” and “udpate”, as mentioned upthread. I also mistype “monitor” as “montiro” quite a bit.
I seem to type envrionment a lot at work.
