Whether you are in the drawing or model view, SolidWorks will bold one of the relations in the Add Relations box once you have selected at least 2 lines.
I assume this is SolidWorks' way of suggesting the most probable/ logical relation to add. Is there a button I can press to accept the suggestion? Enter, Tab, Ctrl or Shift don't seem to work.
As you can see below, I have selected the two lines on the right and left of the shape and SolidWorks has bolded the Parallel relation on the right side of the screen. There must be a key I can press to use that relation instead of having to mouse over and click it. I know this sounds trivial but it will drastically speed up my sketching since I have a TON of simple shapes to draw.
Edit: While in a part file this method doens't matter too much since you get the add relation pop-up menu right next to your cursor after selecting multiple lines. However, while in a drawing file, there is no pop-up menu so this shortcut that I am asking about would really speed things up for me.
