title: Keyboard shortcuts in Eclipse Oxygen
body: <p>I was working in Eclipse yesterday, when my keyboard shortcuts stopped working. They all worked until yesterday. Pressing <kbd>Ctrl</kbd>+<kbd>Shift</kbd> causes a popup saying the cursor does not (yet) have a detectable image. <kbd>Ctrl</kbd> works fine, and so does <kbd>Shift</kbd> + a letter. Only <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+any key causes this error. Even just pressing <kbd>Ctrl</kbd>+<kbd>Shift</kbd> by itself causes the popup:</p>

  <p>I use Eclipse with the <em><a href="http://marketplace.eclipse.org/content/darkest-dark-theme" rel="nofollow noreferrer">Darkest Dark Theme</a></em> plug-in on Windows 10.</p>
  
  <p>What is causing this error, and how can I fix it? Thanks in advance.</p>
