## macro

Define or print a macro called char

### Usage:

> macro [window_type] [key [value]]

> > where key is the name of a valid key (see below), and value is a magic command-line command. If present, window_type must be one of the four window types accepted by the specialopen command: layout, color, netlist, and wind3d. If omitted, the layout window is assumed by default, unless the command has been called from inside a window (using the colon or semicolon escape to the command-line), in which case that window type is assumed.

### Summary:

> The macro command translates keystrokes typed into a layout window into magic command-line commands. When the key key is pressed in a layout window, the command stored in value is executed relative to that layout window. The default bindings are specified in the system `.magic` file, read at startup. These macros may be arbitrarily rebound using the macro command.

> A key macro may be unbound from a command by passing an empty string ("") for the value.

> key is any valid name for a keyboard keypress event. In its simplest form, this may just be the name of the key, such as "g" or "X". The space bar key must be quoted in double-quotes; most other characters may be unquoted. Control characters may be specified by the two-character combination of the carat ("^") key followed by a capital letter, such as "^Z". The use of embedded control characters is deprecated, as it is incompatible with Tcl syntax.

> key may also be specified as any valid X11 name for a key as defined in the include file `keysymdef.h` on UNIX systems. This allows specification of function keys such as "XK_F8" or keypad keys such as "XK_KP_Right".

> Buttons are treated just like keys for the purpose of defining macros. While the official names for buttons in `keysymdef.h` are "XK_Pointer_Button1", etc., the macro command accepts the abbreviated forms Button1, and so forth.

> Finally, key modifiers may be prepended to the key name. Valid key modifiers are Shift_, Control_, Alt_, and Meta_, and may be coupled in any combination. Mouse buttons may also be combined with key modifiers, so, for example, Shift_Button1 is a legal, unique binding.

### Implementation Notes:

> macro is implemented as a built-in window command in magic.
