If you’re looking for ways to streamline your sculpting workflow in Blender, check out Fast Sculpt Assistant, a great add-on for graphics tablet users. While the number of shortcut buttons on the tab is limited, you will be able to sculpt without taking your left and right hands off the pen tablet as much as possible.
Fast Sculpt Assistant makes using various sculpt operations easy in one key, a customizable circular menu split into several sections. In Sculpt mode, the menu can be accessed by pressing Shift + U, which can be changed in the preferences.
