Settings are available from X-Plane's menu:
Plugin > LiveTraffic > Settings.... They are organized in seven collapsable sections: Basics, Input Channels, Output Channels, Aircraft Labels, Advanced, CSL, and Debug.
There are no [OK] or [Cancel] buttons. Whatever you do takes effect at once.
The double arrow buttons expand/collapse all sections.
The search box at the top of the settings allows you to quickly filter options:
Copy & Paste is supported.
[Enter] applies the changed value.
[Esc] cancels the current edit operation and fills the field with the value from before the edit operation. No change is applied to LiveTraffic.
With [Tab] / [Shift+Tab] you can move focus between edit fields.
