Use trackpad for annotation in Preview without clicking Is there a way to annotate PDF's without clicking the trackpad? Something more like writing on paper.

I love that markdown lets us annotate stuff to PDF's using preview. But its slightly impractical - always having to press down.

Is there an app or a toggle which can let me go into writing mode so that I don't need to keep the trackpad clicked while "writing" so to say.
If your MacBook has a Force Touch trackpad, you can use the Draw tool instead of the Sketch tool.


  Draw 
  
  Draw a shape using a single stroke. Press your finger more firmly on the trackpad to draw with a heavier, darker line.
  
  This tool appears only on computers with a Force Touch trackpad.
