Alter sort order temporarily with a key?

I have folders at the top sorted by Name and maintaining that sort independently of the sort for the files below, works great and is generally what I want.
However sometimes I want the folders grouped together at the top but sorted by Date but only temporarily and one time, i.e. I don't want to go into Settings to change things, I just want to suspend and alter that setting.
What would be ideal would be to hold a key and click the Date column and have that sort the folders by Date due to the key being down. I hope that was clear.
Is that possible?

Setting up a button or hotkey that runs the Set KEEPFOLDERSALPHA=Toggle command is probably your best option.
