Formatting
Bold
Use bold text formatting for static interface elements: buttons, tabs, links, options, check boxes, step names, etc.
Italic
Use italic text formatting for selectable interface elements (drop-down list options, object types) and input data you enter (object names, parameter names, parameter values, field values). Also, use italic formatting for error messages, section names if referencing an external document, and state and status names.
Courier (Monospace)
Use courier text formatting, or Monospace as it's known in Confluence, for anything that can be copy and pasted into a command line: URL paths, folder names, file names, etc.
Capitalization
Use sentence case. That means capitalizing the first word of a sentence, heading, title, UI label, or standalone phrase.
Capitalize the various areas of the Devo app: Activeboards, Service Operations, etc.
