title: robot framework how to know if a checkbox is selected
body: <p>I am using robot framework. How can I test if a checkbox is selected?
  I want to run a keyword if a checkbox is selected like:</p>
  
  <pre><code> ${checked} =   Checkbox Should Not Be Selected  xpath=.//*[@id='0,1,1,6']/td[11]/input
      Run Keyword if  '${checked}'  Click Element  xpath=.//*[@id='0,1,1,6']/td[11]/input  and wait
  </code></pre>
  
  <p>i.e. to click there if is not already clicked.</p>
  
  <p>(The code of above is wrong, I know)</p>
