Just a silly observation, I frequently underestimate the number of characters to type for autocomplete to make a match. When it comes to this I am the king of underestimation. In my mind I’m sure nothing else can possibly match the characters I’ve typed to autocomplete a command, so hit tab, only to find 20 other commands that begin the same. I could type 10 characters only to find I should have typed more. Sometimes it seems like I could type zqvw8<TAB> and there will be some other command that begins with the same thing.
