UnrealEd console commands can be assigned to toolbox buttons (see Custom Toolbox Buttons) or to keys.

Binding to Keys

• Open the UnrealEd Advanced Options window
• Advanced -> Raw Key Bindings
• select a key
• Type in the command

Examples

• "POLY TEXMULT UU=0 VV=0 UV=-1 VU=1". This will create a shortcut key that rotates a surface texture by 90°.
• ACTOR ADD CLASS=<CLASS>
