Enter Key to mimic mouse click and double enter to mimic double mouse click. I often use this technique with the enter key to mimic the mouse click. For example, if I’m drawing a wall of a specific length, I will use the numeric keypad to type on the length of the wall and then use the enter key to mimic the mouse click so that I can then draw the next wall. This is a really quick way to draw. If you double hit the enter key it mimics the double mouse click finishing your wall, polygon, etc.
