The  -  key have two main functions. 

It can be used for fixture selection and for assigning values.

A third use is to change the executor page.

## Fixture selection

E.g. you want to select the fixtures in group five but not fixture number two (a part of group five).

Group 5  -  Fixture 2 Please

If you already have selected group five and want to remove fixture two from your selection, you can do this:

 -  2 Please

## Assigning values

The  -  key can be used to assign a dimmer value lower than the current value - Remember, you can't go below 0% on the dimmer.

E.g. you have a selection of fixtures at a dimmer value of 50% and you want to lower it 20%. Here's what you type (you have already selected the fixtures):

At  -  2 0 Please

That would do the trick.

There's a little extra function to the  -  key. If you press it twice it automatically take 10% off the value. So you could have archived the same by pressing the  -  key four times.

### Absolute value or relative value

The description above is about setting a relative value. You can also set an absolute negative value on attributes like pan and tilt.

The difference between a relative or absolute value is a space between the minus sign and the number.

To set a relative value you could write in the command line at - 5 (execute command by pressing Please). An absolute value would be written at -5 (execute command by pressing Please).

If you want to use the keys, then you can press At - (hold it while you type the value) 5 Please, Holding the minus while typing the value removes the space between the sign and the value.

Using the calculator (you can get this by a short tap on the encoder for the value you want to set) you can tap the +/- button to add the sign without a space. For relative values you can use the - button.

## Page selection

You can use the  -  key to change the active page. If you want to go to the previous page you can use the following keys:

Page  -  Please

You can also use calculations. If you are on page five and want to go to page two you could use the following keys:

Page  -  3 Please
