This dialog allows choosing a mission for a starship.

Scroll around using the arrow keys, or use the key displayed next to the mission name, and confirm using Enter; ESC cancels.

When using this dialog from a ship or ship task screen, this dialog will only show missions that the ship can actually perform. For example, a freighter cannot lay mines. Likewise, when used through the Global Actions, some missions will not be shown. As an override, you can always select the "Extended Mission" entry at the end of the list, to enter any mission as numerical values ("M.I.T. interface").

Missions are grouped by category. Categories are displayed atop the mission list. You can select a category for filtering using /, by clicking the category, or by using Alt plus the category's first letter.
