You can use formatting when setting up the letterhead and document template settings:
The formatting in Upp is similar to regular HTML markup, but the “tags” are enclosed in square brackets and their number is limited:
[p] Text paragraph [/p]
[h1] Heading 1 [/h1]
[h2] Heading 2 [/h2]
[h3] Heading 3 [/h3]
[b] Bold text [/b]
[i] Italic text [/i]
[u] Underlined text [/u]
[c] Centered text [/c]
New line: [br]
New page (when being printed): [pb]
Non-breaking space: [nbsp]
