* - Puts the AI in control of a worker's tile improvements. This is not recommended unless you are active in a game but forced to be idle for some turns. Edit
** - Warning, the Buy command in the city window can inadvertently send a Build command to a settler if it is the currently selected unit. Edit
*** - Do provides generic access to legal unit commands, including some options that may be inaccessible by hot-keys or standard menus. For example, "Help Build Wonder" for a Caravan that is already in a city but has no movement points to exit and re-enter.' Edit
