Create your own custom grid! You can add new Actors, either buttons or links to this grid. Use the Next and Previous buttons to move the orange editing selector around the Actors.
You can also remove, or move Actor buttons or Actor links around using the Cut and Insert buttons.
Make changes to Actors by editing the text fields, and then use the Apply Actor Changes button to update the selected button.
Don't forget to edit the page title, banner (if you want one,) and page name (which I usually make the html filename.) Use the Apply Page Changes to update the page.
There is also an option to enter a "note" which is read out loud on page open. The text for the note, however, is not visible.
After making changes, close the editing screen. Then use the browser's "Developer tools" to copy the "OuterHTML" of the "html.." tag and paste it into text editor.
Save the result from the text editor as an html document. Be sure to save the new html file in the directory structure where all the tts_min resources are stored.
Don't be tempted to click on Actors while you are editing. If you navigate away from the page any changes will be lost!
