I sympathize with reluctance to add new commands, especially when one is very similar to an existing one. > By contrast, what TAB TAB TAB... does inside completion for commands > is a general feature, not similar to any other. > > Users will forget commands that they learned, but I think they will > hardly forget this. ...but making a general feature (and completion-at-point is a general interface which we use in many context) more complex can be much worse. TAB and 'TAB TAB' already do different things. Now, what happens if a third 'TAB' will switch the completion tale? The user will have to count how many times they pressed TAB now. Did I press it one or twice? If once, next press will pop up the Completions buffer, if two: switch to another completion table. What if I press TAB 4 times, what will happen? Or ok, I pressed TAB a few times, but forgot to count. Which completion table is it using now?
