Regarding the last point specifically, there is an established texting convention. Say you you (or autocorrect) have made a mistake and typed word A and you have already sent the message, but really you meant word B. Then, if you notice this mistake (granted, if), it is common convention to simply reply “*B”. Then, when the recipient reads to the mistaken word A and wonders why the word A seems out of place, they can look at the subsequent message and substitute B for A, without you even having to explicitly designate which word you made a mistake in (this is still sometimes necessary, but rarely).
