I was surprised when I first came across this, to know that this was apparently such a common typo - since I don't ever recall doing this particular typo myself, even though I'm prone to character-transposition typos. But then I realized, I rarely ever do `ls` itself - it's always either `ll` = alias for `ls -lh` or `la` = alias for `ll -A`. And those seem less typo prone, somehow.
