Context-sensitive menus are those that appear in response to user action (typically a mouse click) and whose contents are determined by the context (area, field, and so on).
There are numerous locations where you can right-click a field label or data in a field, or the button on the Information bar to display a context-sensitive menu. Some menus commands have sub-menus. See also: Move a field.
The menu commands vary according to which line or item in the word focus box you right-click.
For an example, see About the Dictionary-Context style.
This example shows two different menus that can appear on a word, here in a Baseline tab. The first picture shows a word flagged with a wavy red underline. The second picture shows the same word, but without the spelling flag. (Cut and Copy are enabled when the word is selected.)
