title: Disable ubuntu keyboard shortcuts
body: <p>I must have accidentally activated some keyboard shortcut function because every time I press certain keys such as <kbd>w</kbd>, <kbd>a</kbd>, <kbd>s</kbd>, <kbd>d</kbd> they act as shortcuts to things. For example if I press <kbd>f</kbd>, the search function appears. How can I stop this so I can type these letters again?</p>
  
  <p>Thanks</p>
