You must first understand how styles work.
Three layers are available and the shallower override the deeper.
The lowest level is paragraph style. As the name implies, you act on the layer by giving a style to a whole paragraph. You reset it by giving a “neutral” paragraph style, in principle Default Style, which, because of this usage, should never be modified or actively used in the document (unless you know what you’re doing).
The second layer is character style. You act on this layer by giving a style to a selected range of characters. Contrary to more complex DTP programs like Quark XPress®, any character can receive only a single character style, the latest applied overriding the previous one. You reset the style to the paragraph style by applying character style Default Style.
This latter style is not a real style. You can’t modify it. Its sole purpose is to remove any character style.
The top layer is direct formatting. You set attributes with the buttons in the toolbar(s) or their shortcut equivalent. They are erased with Format
→ Clear Direct Formatting
or Ctrl+M
.
I suspect this third layer was provided to avoid the burden of setting up a consistent set of styles for short one-shot documents and maybe also for “compatibility” (i.e. not upsetting users even if it is “wrong”) with other text processors.
Every layer is independent from each other. Resetting one does not reset the others.
To answer your question about resetting character style:
- Select the paragraph content (e.g. quadruple click)
- Apply character style Default Style
