How to set a hotkey for mouse extra buttons in Editor Preferences?

Hello!
I want to change some hotkeys, for example “Focus Selected” to my “mouse button 4”, but I cannot do that. When I press the side button on my mouse, UE doesn’t apply that hotkey. I already use my mouse’s side buttons in Blender for the same function and there are all okay with assigning. Can you help me, please? Thank you!

Hi there!

I’m afraid those Keyboard Shortcuts are indeed only what the name suggests, a shortcuts meant to be bound to a keyboard key.

Only thing I can suggest is to use other software like AutoHotkey in the background to trigger an event on desired mouse click and create input on keyboard itself which you bind in Unreal.

Hope it helps!
