markItUp! is a jQuery plugin for turning any text-are into a full blown markup editor.
Its main advantage over other markup editors is its flexibility; whereas you couldn’t make a custom editor out of TinyMCE (well, not an editor that would be easy to update), markItUp allows for endless customization.
There is a number of interesting features that markItUp! has:
- Keyboard shortcut support;
- Easy integration;
- Customizable skins and Ajax previews.
