The status of the editor is displayed using graphic indicators. They inform the user about things such as:
Editing mode (numeric/alphanumeric, language-specific modes)
Character case
Predictive Text status
Available space
When the editor is in the main pane, the indicators are located in the Navi pane. A Data query that resides in a pop-up window has its indicators within the window.

The API to use for editing indicators is the Indicators API. For the navi pane, use the Navigation pane API.
