title: VSCode arrow select mode how to get out?
body: <p>I don't know how did I get into this mode, but whenever I press the arrow buttons, the cursor moved and selected the text it passed. As if the <kbd>Shift</kbd> key is pressed.</p>
  
  <p>What is it and how to get out? </p>
  
  <p>I have to close and reopen vscode to clear it.</p>
  
  <p>Edit: The mode is entered by pressing <kbd>Ctrl</kbd>-<kbd>Space</kbd>. Seems an Emacs mark set mode.</p>
