As Barry noted, if the T&R palette is not visible, you may not be aware that T&R is turned on. For that reason - and ease of access - I always have that palette docked with my other palettes as shown in the attached screenshot of my normal Work Environment. Any organization that works for you is a good organization of course.

PS As a tangent / off topic... I continue to be frustrated that Graphisoft's default WE has the Info Box horizontally at the top of the screen... which let's you view... and modify... very few settings. I wish they would distribute a few Work Environments (WE) so that new users could try working with the Info Box at the side as shown here... where it scrolls vertically with the mouse 'wheel'. My experience is that most people just work with what is delivered, assuming that Graphisot delivered it as an example of 'best practice'. But, best practice is what works best for you... and exploring the Work Environment options is worth the time. OK; off my soapbox.
