Add a way to show only const function in autocomplete

I sometime use autocomplete as a quick "exploration" tool on an object to see the available methods.

Being able to show only the const/non-const methods of an object would be useful to me.

My desired workflow would be <nameOfTheObject> <dot> (at this point all the methods are shown) <alt (or shift?)> to toggle between all methods/const methods/non-const methods.
