I’m sorry for the really basic question, but I’ve done some searching and apparently my search criteria are too general or simply just wrong.
Background: I heavily customized Blender to act more like Maya and other apps I am comfortable with. It was great because I was able to get my work done and not fight with a new-to-me interface. But now I want to learn Blender properly (and follow some paid tutorials) so I have reset my settings back to default (except Maya-style navigation and left mouse select - including alt-left rotate etc.)
One thing that I noticed is that I can no longer de-select items by simply clicking on an empty part of the 3D-view. I was able to do this under the Maya preset but searching through the keyboard bindings I am not able to find anything that jumps out at me as being the thing to change.
I would like to modify Blender so that I can once again left-mouse click on empty space to clear the selection. The only thing I have found so far is (De)select all which is assigned to the letter ‘a’. But this toggles the selection off, then the next time it selects all (exactly as advertised). So this doesn’t seem like the right place to make the change.
Can anyone point me to the name of the setting that I need to change to re-enable this ability to de-select by clicking on the empty space in a 3D view?
