title: Is there a way to leave the Okular highlighting tool on permanently?
body: <p>I found out I can highlight pdfs with okular in-file by the review tool, but everytime I use the highlighter, it gets turned off afterwards again, so to highlight the next piece of text I have to activate it again. </p>
  
  <p>I would like to change this behaviour to 'toggle' on off by clicking (or pressing 4), and not have it turn off automatically.</p>
  
  <p>I saw <a href="https://superuser.com/questions/584017/customise-okular-to-modify-highlight-tool-properties">here</a> that the tools can be modified, but it doesn't mention toggling.</p>
