It would be useful to be able to select multiple lines of the "in-memory" history for editing/deleting/copying. Permit multiple individual line selection and select-all, with the usual keys and mouse actions, in the command history window (page-up). Allow the selected lines to be copied, deleted and/or loaded into a editor (user setting/option). A default editor, such as wordpad, should be defined if the user doesn't define an option. Granted I can save the entire cmd history to a file and then load it into an editor, perform my edits, and then read the resulting file into "in-memory" history. Allowing this from the page-up window would be easier, faster, and more elegant. More automation please.
