My idea is a standard keyboard control key for a laptop or a regular keyboard. This key can be resized to fit any build. The reason I chose this is because it is more likely to get popped off than an inside letter key. I think this a useful idea in the long run. It works well on the keyboards we have but I have not tested it on a laptop thus far. The sides are rounded and it has an insert.I love the simplicity of the design itself, the chance of a key breaking is not very good but if one were to break who would’ve thought to bring an extra key with them. I personally think that this design will not be overlooked, but at the same time I think that the simplicity will also ultimately be its own downfall.
