Use case or problem
On macOS, there’s no hotkey (nor a possibility to set one) for renaming a file or folder, you have to right-click every time you want to do it.
Proposed solution
On macOS, rename files and folders by pressing space when the file/folder is selected, following macOS’ system hotkeys.
Current workaround (optional)
Right-clicking each time to rename
