title: In Vim, replace all occurrences of current term under cursor
body: <p>If you press <kbd>*</kbd> in Vim, the editor will search for the next occurrence of the term in the same file. It saves you from having to type out the term. </p>
  
  <p>Is there a quick way to replace the term currently under the cursor with a new one? One character to issue the command, typing in the new term, then <kbd>Enter</kbd>.</p>
