New in the March 2018 release
Adobe Muse now supports copying styles across elements in the Design view. Previously, you had to search for a specific style from the panel and apply it to another text or object in your design. Now, you can simply copy a style from a page element and paste the style attributes to another element in a single click.
You can copy and paste character styles, paragraph styles, bullet styles, states, and link styles. To copy style attributes from one element to another, right-click and copy the style. Select the element where you want to paste the style. Right-click and select Paste Attributes.
Apart from copying all the attributes, you can also selectively paste the attributes that you want to copy. To know more about copying and pasting style attributes, see Copying and pasting styles in Adobe Muse.
