title: How to turn off a weird "box" cursor and selection behavior in Netbeans?
body: <p>I have some kind of weird behavior in Netbeans. I guess I accidentally entered some key combination which messed up the cursor and selection behavior. In the image you'll see what I mean: normally, if you select text across multiple lines, you'll see the behavior on the right screenshot.</p>
  
  <p>But I have the behavior on the left screenshot. Also, trying to insert text at a certain position with Shift, inserts it some positions to the right (= not where the cursor is). Additionally, when the cursor blinks, it appears dashed.</p>
  
  <p><img src="https://i.stack.imgur.com/TUmvv.png" alt="Netbeans comparison"></p>
  
  <p>The fact that the selection in the left screenshot is drawn nicely doesn't make me think of a bug, but rather of a feature. I can't seem to find the key combination to turn it off again. </p>
  
  <p>So my question is, what is this feature? Why does it exist and with what key combination did I turn it on?</p>
