Why CommonUI needs these

CommonUI drives every widget's universal confirm (click) and cancel (back) from two shared input actions. Create two plain Enhanced Input assets — IA_UI_Confirm and IA_UI_Back (Digital/bool) — then point CommonUI at them.

Wire them in DefaultGame.ini

ini
[/Script/CommonInput.CommonInputSettings]
bEnableEnhancedInputSupport=True
EnhancedInputClickAction=/Game/Input/IA_UI_Confirm.IA_UI_Confirm
EnhancedInputBackAction=/Game/Input/IA_UI_Back.IA_UI_Back
Legacy path
Projects not using Enhanced Input for UI instead set DefaultClickAction/DefaultBackAction with a CommonUIInputData DataTable — the Enhanced Input route above is the 5.8-era default and what the rest of this course assumes.
