How to change default properties for markup annotations with JavaScript

[izzycamm]

Is there a way to access/change the default properties for a markup annotation using Javascript?  Since it is a dynamic toolbar and dialog based on the type of markup selected I can't find the properties or methods.  A second question would be how to find the properties/methods for a dynamic toolbar or dialog.  I have searched the documentation and can't seem to find it.

Thank you so much for any assistance provided.

Can the user that did the mark-up fill it out themselves

I am looking to create a toolbar items to change the highlight to a specific colors in one click. This change would become the default color until another color is selected or custom color selection is stopped (going back to yellow). I need to use predefined colors for specific text that is highlighted.
