Earlier quoted context omitted.
That's half-right, I think. The question is, when using a command like "change until" or "change forward", i.e. 'ct' or 'cf', what will the effect be? In the case of 'ct', you're going to delete up until the letter, whereas in 'cf', it will include the letter you're targetting.
> "change forward" [...] 'cf' "change find", you mean.
This goes beyond "counterintuitive-ness"... After a few years working with vim, I find myself unable to easily recall how to do some basic operations. Vim is counter-retentive for me as well. Thanks OP, I'm gonna start playing with Amp now!
