I am a vim newbie and some time ago I installed a plugin that enables previewing color schemes by repeatedly pressing a key. It is not the
colorscheme command which lists the schemes and switches to text in the editor after you select it.
This one I am talking about actually switches the scheme in use when you press the cycling key, more like a live preview, and you press the enter key if you find the one you want, or escape to cancel to retain the current scheme.
Can anyone tell me the name of the plugin?
