As well as assigning values for parameters, you will sometimes want to remove parameter values from editors. For example:
You no longer want to use a particular fixture in a cue, scene or palette.
You decide to have the colour of several fixtures controlled by a different cuelist on another playback. To do this, you need to remove colour parameter values, so that they don't take over control of the colour parameters under the LTP rule. See HTP and LTP.

If you want to clear the entire contents of an editor, use the Clear key. |
To remove selected fixtures from an editor (known as ‘knocking out’), press the Knockout button on the Main Toolbar. For example:
Fixture
1Thru5Knockout : removes Fixtures 1 to 5 from the editor.
Group
2Knockout : removes all fixtures in Group 2 from the editor.
You can remove specific parameter types from the selected fixtures in an editor using fixed kinds or user kinds keys:
Colour, Knockout : Select the parameter type and press Knockout
You can remove individual parameters from the selected fixtures in an editor:
Hold Knockout and move the relevant parameter wheel, or press the relevant button on the Slot Toolbar.
Hold Backspace and move the relevant parameter wheel.
Hold Backspace and press the relevant parameter type key; this gives single-handed operation.
You can remove the values from the currently highlighted cells in the Programmer by pressing Pig + Backspace.
