You want to give the title of your paper a personal touch? This is how you can add a textile modifier:

1. Click on settings to access your paper's settings (below your avatar)

2. Edit your title:

•  superscript : make it ^_high_^ = make it ^high

• subscript : make it ~*_low_*~ = make it _low

• _italics_ = italics

• * bold* = bold

• _* bold italics*_ = bold italics

So if your paper's title shall look the one above, simply set it up like this: 

*Birgit's* ^_Paper.li_^

3. Save your changes!
