title: How can I enter a literal <TAB> character in IntelliJ/IDEA/PyCharm?
body: <p>My configuration indents with four spaces, and I want to keep that. Occasionally (e.g. in a Makefile) I want to input a literal TAB character.</p>
  
  <p>How can I force the IntelliJ-IDEs to input a tab or space, when it would not do so when I hit tab or space in that instance?</p>
