Can I temporarily turn off room selection?

[George-Costanza]

Hi,

 Is there a way to temporarily turn off room selection? When I am zoomed in and using some of the tools the cursor changes to selection mode immediately after using the tool,  and then I mistakenly select the room and the whole floor becomes selected.. Then I am stuck and seem to have to zoom out to clear the selection so that I may zoom back in an continue the work.

 

 I thought I knew how to turn off room selection, but now I can't remember if or how. Can I turn it off?

 

Thank you.
