Stay in Annotation mode in Okular?

I am trying to markup a PDF that I have in Okular. I would like to make a lot of notes with my Bamboo tablet, but every time I lift the pen, I go back to the default mode. This obviously defeats the purpose.

Is there a way to stay in Annotation mode across strokes? Or is there another tool in Ubuntu that will do what I want? Thanks!

With a single left mouse button click on an annotation tool button you can use a tool once. If you e.g. want to highlight all important parts of a text, you can activate that tool permanently by double clicking on the tool button. Press the Esc key or click the tool button again to leave the permanent mode.
