DESCCRIPTION The Input field of Calculator is really weird given it is part of a modern Operating system. - there is no Cursor - you can't select text - pressing backspace does not delete the last digit you typed - there is no history, you cannot fix a typo by pressing Ctr+Z - pressing "Delete" deletes the entire formula ADDITIONAL INFORMATION I am aware, that this is how old-school physical calculators used to work, but I think it is impractical in a modern Desktop, for the meta discussion, visit Ticket #463809.
There are 5 issues reported in here; we need one bug report per issue please.

So please file two new bug reports for these: > - there is no history, you cannot fix a typo by pressing Ctr+Z > - pressing "Delete" deletes the entire formula
> So please file two new bug reports for these: okay I've summarised it here as I felt these bugs will have the same solution ... but anyways, I am currently getting familiar with kde development utils and will assign myself the things I think I can fix.
