 Calling Sequence CurrentContext[command](arguments) command(arguments)

Parameters

 command - command exported by the current context menu module arguments - arguments to the command

Description

 • The CurrentContext package represents the current context menu structure. Using the exports of the CurrentContext package, you can change the current context menu structure and functionality.
 • In the standard distribution of Maple, ContextMenu:-CurrentContext is an alias for the global package StandardContext, which is the built-in context-sensitive menu system.
 To change the entries that appear in the current context menu, use the Entries subpackage.
 To change the organization of entries in the top-level context menu, use the Categories subpackage.
 To change the entry generators or queries that are used by the current context menu module, use the EntryGenerators or Queries subpackages respectively.
 • The HandleExpression command returns the contents of the context-sensitive menu for a given expression. Though it is generally used only by Maple when generating a context-sensitive menu interactively, it is useful for testing that modifications or additions to context menus behave as expected.
 • Each command in the CurrentContext package can be accessed by using either the long form or the short form of the command name in the command calling sequence.
 As the underlying implementation of the CurrentContext package is a module, it is also possible to use the form CurrentContext:-command to access a command from the package. For more information, see Module Members.
