When I click on DEFAULT font in my notes, it doesn't produce the font that I have set as my default. Also, it would be helpful to be able to click a letter (e.g. "O" to take me quickly to Open Sans font), but this instead puts that letter into my notes. Any work arounds for these issues?
If you are using the desktop platform:
Press [Ctrl+A] to select all text in the note.
Click the default tool in the Notes menu (looks like a circle with backslash) to turn the highlighted text back to your default font. Sort of.
My default font size is 11 points, and clicking that tool turns it all into 12 point. (shrug) One more click sets the font size.
Note: This step also removes all formatting: Bold, italic, indent...
