Context menu

The term Context Menu refers to a menu accessed by single clicking on something (or holding down shift, then single-clicking on something, if one has selected the option to handle it that way).

Several game mechanics are accessed this way, including Item Insurance, and the old Quest system. (The newer quest system is accessed by double-clicking on the "quest giver" NPCs and the quest log is checked via the paper doll.

Though Context Menu is the common, and formal, term for this mechanic, some documents refer to it as "Contextual Menu."
