Here is my suggestion for making the Help for TrayMenuMode clearer for the novice: Changes how Tray items operate. The defaults (value 0) are: The AutoIt items Script paused/Exit are appended to the user’s menu itemsItems created with TrayCreateItem(..,..,.., 1) act like auto-radios; all others act like checkboxesIf an item has the $TRAY_DEFAULT state, making it the default item, this item is shown in bold, and double-clicking the tray icon executes this itemOther possible values are 1 , 3, 5, 9, 11 and 13. They remove or change features of Mode 0, and are additions of the following numbers:1: The AutoIt items Script paused/Exit are not shown2: Items act neither as checkboxes not as auto-radios, unless specified by calling TrayItemSetState(..,$TRAY_CHECKED)4: Double-clicking the tray icon has no effect. An item with the $TRAY_DEFAULT state still shows in bold.8: Several radio-like items in a group can be selected at the same time, i.e. they act as manual radios not auto-radiosI encourage comments, corrections and suggestions. relates.
