## Labels
|
|
|
|
|
|
In this tab you can lock or hide objects of a certain label.
|
|
|
To change the color for a specific label,
|
|
|
you need to go to the task page and select the color by clicking the edit button,
|
|
|
this way you will change the label color for all jobs in the task.
|
|
|
|
|
|
|
|
|
|
|
|
**Fast label change**
|
|
|
|
|
|
You can change the label of an object using hot keys.
|
|
|
In order to do it, you need to assign a number (from 0 to 9) to labels.
|
|
|
By default numbers 1,2...0 are assigned to the first ten labels.
|
|
|
To assign a number, click on the button placed at the right of a label name on the sidebar.
|
|
|
|
|
|
|
|
|
|
|
|
After that you will be able to assign a corresponding label to an object
|
|
|
by hovering your mouse cursor over it and pressing `Ctrl + Num(0..9)`.
|
|
|
|
|
|
In case you do not point the cursor to the object, pressing `Ctrl + Num(0..9)` will set a chosen label as default,
|
|
|
so that the next object you create (use `N` key) will automatically have this label assigned.
