# Set The Following Properties

This is a Basic Procedure tutorial page. It explains how to perform a single procedure which is required in many different contexts.

The Actor Properties Window holds all the settings for an actor. It always updates itself to display information for the currently selected actor or actors.

## Select the actor

## Open the window

If the properties window is not already open, open it now. Do one of:

- Actor Context Menu → <classname> Properties (the first item in the menu)
- Press the button on the toolbar (highlighted in the screenshot below)
- Press the F4 key
- UnrealEd Main Menu → View → Actor Properties

The Actor Properties Window. The currently selected property is Events → Event.

Within this window you can edit the properties for the currently selected Actor. Note that this window isn't a dialog box, there's no "OK" button: changes to properties affect the actor immediately.

## Set the property

Every actor has dozens of properties, organized into groups. Each group can be expanded or collapsed by clicking the [+] or [-] sign to the left of the name. On Unreal Wiki, we write the name of a property like this:

PropertyGroup → PropertyName

To find this property, first find the group, expand it, then find the property. Both groups and properties are listed in alphabetical order.

To the right of each property name is the value it currently holds. To change this value, simply click on it: it turns into an active text field into which you can type. Within this field, you can use the mouse to position the cursor or select text.

### Tip 1: cut, copy, paste

The usual Cut, Copy, Pasty keyboard shortcuts work within the text edit fields. You can copy values between properties, and between actors. This is particularly useful when matching tags.

### Tip 2: maths expressions

Typing a numerical expression will store the result. For example,

     64*4

will set the property to 256. In UnrealEd 2 you need to type

     =64*4
