I use Amphetype. It's buggy, but good.
I was wondering if anyone had a list of the most common length 3, 4, 5, etc. strings for typers of English. I could use a list like that with Amphetype fairly easily.
Wordlists are OK, and I have found some. But, I was hoping for just the strings, since long words tend to be higher in concentration of certain letter combinations (like "tion" for example, which isn't in any small common words)
