OP has figured it out already. For others who stumbled here…
Based on the standard Blender (2.8) keymap tradition and LEFT select, also to exercise my memory…
Blender (G) Move = Screen Space Move. (corresponds to tiny white ring in the middle of active gizmo)
Blender [R) Rotate = Screen Space Rotate (corresponds to outer big white ring in active gizmo)
Blender (RR) Rotate = Roll Rotate in random directions (corresponds to the white semi-transparent sphere in active gizmo)
Scale (S) = Scale all direction (from your Pivot of choice)
Blender calls Screen Space transformation “View” or window-axes transform. Useful only if you use orthographic view a lot. Most new users will end up with precision-transform using Active Gizmo (which also informs users of global/normal mode or median/ active pivot).
Now to the Select tools.
Most selections (modeling or posing) are done with 4 (W) Select tools: Select, Select Box, Select Lasso, Select Circle
Hit W to cycle to get to your fav Select tools. (I find their buried in drop-down state ridiculous. MOST FREQUENTLY SWITCHED TOOLS should all be buttons, same with pivot/ orientaiton. Or at least, they should be a Pref option)
Most people from other apps tend to use Select Box mode. This means you can click drag on empty background to select objects or bones. ZBrushers will like Select Lasso, but Select Circle is quickly become my favorite for modeling.
You can also hit B to box select the old way. But I plan to save the B key for other frequent operations.
You can also hit Shift Space to call up a mini Transform menu. (But what for?)
Since I use Select Box a lot, I’m thinking of assigning a special key for it. Maybe Q.
That’s it for now. Happy Blendering!
