This is negligible with a bit of Emacs lisp. However, as stated
earlier, there are /many/ cases where this is useful. Following the
DRY principle means a more abstract function would be better to use

One may use higher order functions to create an abstract form that
handles toggling, and then the caller can wrap this call in a new
function if they wish to use it in a keybinding. This format or
function if they wish to use it in a keybinding. This format or
construct is kinda common (using a higher order function and wrapping
it in an interactive function for use in a binding), so I created a
macro that further wraps this functionality, creating a custom

The macro asks for a function name, a buffer name and the function
necessary to create that function. It then generates a function with
