## help

Print the command list and usage for all of the 3D viewing window commands.

### Shortcuts:

> Key macros ? and h implement the command help.

### Usage:

> help

### Summary:

> The help command prints the command list for commands known to the wind3d window, along with a line of text summarizing the command usage. It is separate from the help procedure for magic as invoked from the console (terminal). It does not, for instance, accept a "pattern" argument.

### Implementation Notes:

> help is implemented as a built-in wind3d window command in magic. It can only be invoked from a window created with the specialopen wind3d command, or the render procedure. Note that the wind3d window is only available when magic is compiled with the OpenGL graphics option and invoked with magic -d OGL.

> Note that macros of the wind3d window are hard-coded, and cannot be changed with the macro, gmacro, or imacro commands. There is no "`:`" macro for entering commands; to enter commands from the command-line, use the tk_path_name command. The default Tk path name of the wind3d window is "`.magic3d`".
