# Markup

The **Markup** tool can be used to create editable screenshots in UDiTH. When you add a Markup, a screenshot is taken from the current camera position.

1. Go to the **Files** tab and select **Markup** from the **Add** drop-down menu.

2. Enter a name for the **Markup**. 3. Click the **(Un)Lock** button next to the Markup to open the editing tools.

4. The **Markup** editing tools are available in the additional context menu on the right:

	Show initial screenshot displays the view that was captured when the Markup was created, without any user interface elements.
	Undo/Redo undoes a single action or restores it if it was undone.
	Draw free line creates a freehand line that follows the movement of the mouse or finger in any direction.
	Draw straight line creates a straight line in the direction of the mouse or finger movement.
	Draw orthogonal line creates an orthogonal line aligned with the X and Y axes.
	Draw rectangle creates a rectangle whose size is defined by the mouse or finger movement.
	Draw oval creates an oval whose size is defined by the mouse or finger movement.
	Draw text creates a text field at the position where you click. The font size and colour are defined by the pen settings. If you select existing text, it can be edited.
	Move allows you to move the currently selected element in any direction on the P&ID.
	Eraser removes parts of positioned markups graphically. It does not delete entire objects, only the parts over which the tool is moved, similar to using a sponge.

	Pen templates set the drawing pen to a fixed size and colour. The last template is opaque.
	Pen definition changes the size and colour of the pen.
	Pen colour - Click the colour panel to open additional colour options. The slider controls the transparency.
