Did you know that you can use keyboard shortcuts to quickly rename assets?
If you would prefer to watch the video version, check it out here
Normally to rename a file there are two methods: Awkwardly Double Click on an asset (you have to get the timing correct else it opens it or nothing happens) or you can Right-Click and use the Rename option.
However a much quicker and smoother way to do it is to use the keyboard shortcut F2. You can use this pretty much everywhere: assets in the content browser, folders, assets in the scene, custom event blueprint nodes, blueprint variables, blueprint components etc
This is a really quick and easy way to rename things and one that I use all the time.
