title: Multi-line block select using the keyboard in IntelliJ IDEA on a Mac OS X
body: <p>I've recently switched from Eclipse to IntelliJ IDEA 13.  I use the VI keybindings.</p>
  
  <p>One non-vi thing I am used to doing in Eclipse is using <kbd>Shift</kbd> + <kbd>↑</kbd> / <kbd>Shift</kbd> + <kbd>↓</kbd> to block a few lines of text.  The behaviour of this text selection in Eclipse is the same as almost every other text input widget I've ever used.  Typically I do one of two things after making the selection - delete this block or comment it out (<kbd>⌘</kbd> + <kbd>/</kbd>). </p>
  
  <p>I have no found equivalent keyboard-only multi-line selection function in IntelliJ IDEA 13.</p>
  
  <p><kbd>Shift</kbd> + <kbd>↑</kbd> does not start a block selection - it seems to page the cursor up and down the screen.</p>
  
  <p>If I use the mouse to start making a selection, then the arrow keys <em>do</em> extend the selection.  However, I'm unable to <em>start</em> a selection using the keyboard alone.</p>
  
  <p>I'm aware of the <kbd>⌘</kbd> + <kbd>W</kbd> <em>ever-outward-growing smart element selection</em> - but if you then use the arrow keys, the selection is lost, not extended.</p>
  
  <p>How can I start and then extend a selection region across multiple lines using the keyboard only on Mac OS X (that works with the VI keybindings enabled)?</p>
