Although beloved by many developers, the Vim text editor has a well-earned reputation for being somewhat difficult to use. But Editor Keys aims to change that with a new Vim Keyboard Cover. The silicone membrane fits neatly over a MacBook Pro keyboard and succinctly explains the Vim features and shortcuts associated with each key.
The covers retail for £27.99 in the UK, where they were designed, and they are also said to protect against dust and spills. Unfortunately, there aren't versions for other types of laptops and keyboards — just the MacBook Pro for now.
