In the command line:

  • copy copies anything as a string.
  • Right-click a node in the Inspector and click "Use in Console" to create a tempN variable for it.
  • cd switches the JavaScript evaluation context to a different iframe in the page.
  • console.table() displays tabular data as table.
  • help opens the MDN page describing the available commands.
  • :screenshot <filename.png> --fullpage saves a screenshot to your downloads directory using the optional file name. If no filename is included, the file name will be in this format:

    Screen Shot date at time.png

    The --fullpage parameter is optional. If you include it, the screenshot will be of the whole page, not just the section visible in the browser windows. The file name will have -fullpage appended to it as well. See Web Console Helpers for all parameters.
