Yeeees, thank you
No worries, I didn’t actually do anything! Be sure to thank Rama though! :>
By the way, An awesome thing you can do: Whenever you have a question like this, boil it down to the core issue such as “Key Bindings” and then go to UnrealEngine.com > Learn > Documentation. When you put your keyword into the search box, it’ll bring up every forum post, documentation, wiki, BlueprintAPI and Answerhub question about it!
From there, you can filter what you need and find the answer you’re looking for :>
