A
menu which appears in response to a
user action (typically a
mouse click) and whose contents are
determined by which
application window was clicked or has
the input focus.
Most GUIs use a secondary mouse button (right or middle) to
call up a context-sensitive menu as the primary mouse button
is normally used to interact with objects which are already
visible.
The context-sensitive menu often contains functions that are
also available in a
menu bar but the context-sensitive menu
provides quick access to a subset of functions that are
particularly relevant to the window area clicked on.
The
RISC OS WIMP uses only context-sensitive menus (always
invoked using the middle mouse button). This saves screen
space and reduces mouse movement compared to a
menu bar.
