To enter the Blind keyword in the command line, use one of the options:

- Press Blind 
- Type **Blind**
- Type the shortcut **B**

## Description

The Blind keyword is used to suppress the output of the live programmer. It is possible to program without putting the content live. Disabling Blind activates the programmer and the changes made during the mode. 

Use the [DMX sheet](/grandma3/2-3/patch_dmx_sheet/) to see that the output is set to 0.
