Recall last used tool keyboard shortcut

When using other apps, or even ARA Melodyne have a shortcut to jump back to the last used tool; such a good idea and just a little but important detail to help alleviate fatigue.
I was introduced to this idea prob 2 decades ago on Archicad and what a time saver

Bumping ^^^

Ok Ill mark this as a fail…
no other users cognisant or considered of no value
