Changing IDLE's settings on Windows

  1. Open the version of IDLE that comes with Python 3, which you installed in the previous task. (If you can’t find it, you should be able to search for it from the Windows start menu.)

Warning

If you have more than one version of Python installed, make sure that you use a version of IDLE that comes with Python 3. Do not use a version that comes with Python 2.

  1. Click the Options menu in IDLE, then click Configure IDLE.

  2. In the resulting window, use the drop-down box to change the font size to at least 12 points. Important: For the Main Font, you should use a fixed-width font in which each character has the same width. Options include Lucida Console and Courier New.

  3. In the same window, select the Keys tab.

  4. In the section of the Keys tab called Custom Key Bindings, scroll down to find the line for history-next.

  5. Click on the line for history-next and then click the button labeled Get New Keys for Selection. In the resulting window, scroll down to find and select Down Arrow. Then click OK.

  6. When prompted, enter a name for your new Custom Key Set. You can just use your first name. Click OK.

  7. Click on the line for history-previous and then click the button labeled Get New Keys for Selection. In the resulting window, scroll down to find and select Up Arrow. Then click OK.
