title: Changing variable name in Spyder
body: <p>I have a program with many formulas and variables. I need to change the name of some of these variables. Is there any command or function in <a href="https://github.com/spyder-ide/spyder" rel="noreferrer">Spyder</a> that can help me change all the names in one step?</p>
  
  <p>I am looking for something like the Matlab's MAIUSC+ENTER.</p>
