Macros

Macros are not really modules but can behave like modules.

To create an empty macro, hold [Alt] and Left-double-click.
To toggle open / close of a macro, hold [Alt] and Right-click on the macro.
To change size of a macro, hold [Alt] and left-click and hold left mouse button down while moving the mouse sideways. Left shrinks, right expands.
To change background opacity, hold [Alt] and scroll with the mouse wheel. This is most useful in performance mode.
To expose a parameter from a module to outside the macro (in or out), start a connection and drop while the mouse is over the macro's surface. This creates an "alias".
To connect a module inside the macro to a module outside the macro, just form a regular connection.
To move one or more selected modules into a macro, hold Ctrl+Shift and left-click-drag.
