- How to delete selectively from history.
I am trying to use this WolframAlpha app (free if I remember) to portray some 3D surfaces. Having succeeded up to a point I don't want to switch to anything else while I complete an investigation bearing on some homework help.
Although I have read stuff claiming Wolfram is a smart system that can understand natural language I find just like anything with computers I cannot do anything of the above if it is not spelt out rigidly according to the prescriptions of example illustrations with their ( {} , ] etc. I also find that in >80% of cases I cannot do anything if I do spell out rigidly according to the prescriptions of example illustrations with their ( {} , ] etc! Result I have a History column 90% of which is useless and making it hard to find my useful results. So I would like to delete the rubbish, one item at a time.
Top Left there is a thing saying 'Clear'. I suppose this deletes just the one item but it comes with the dire warning it cannot be undone. I have tried to find out what this actually does, but could not find anything telling me this simple thing in WolframAlpha or outside - though there is plenty about how to perform massacres of data which seems a large preoccupation
So can anyone reassure me?
