todo-add-category
todo-add-category is an interactive compiled Lisp function in `todo-mode.el
'.
(todo-add-category &optional FILE CAT)
Add a new category to a todo file.
Called interactively with prefix argument FILE, prompt for a file
and then for a new category to add to that file, otherwise prompt
just for a category to add to the current todo file. After
adding the category, visit it in Todo mode and if option
`todo-add-item-if-new-category' is non-nil (the default), prompt
for the first item.
Non-interactively, add category CAT to file FILE; if FILE is nil,
add CAT to the current todo file. After adding the category,
return the new category number.
