Trying to Automate Changing Background Color of Text in Pages app for Mac

I want to print text that is highlighted in the Mac Pages app, HOWEVER, you can’t print highlighting.
If you want to print text that “appears” highlighted you have to set the background color of some selected text. This option does not seem to have a keyboard shortcut. Does anyone now how to automate this with short cut of any kind (built in or Keyboard Maestro, etc.)?
