There are commands which take multiple inputs. My question is about the possibility of defining a new command which take all the inputs of another command at one time (separated by commas).
As an explicit example, after activating calendar (by
M-x calendar), if one executes the command
M-x calendar-goto-date, then it asks the
year (put 2017), then the
Month name (put July), then the
day (put 7). It would be nice to give these inputs at one time like
2017,July,7. This is just an example, the question also arises in other situations.
