The Vim Marker Sharpener plugin brings reliable markdown formatting to users working in Vim mode, especially in VISUAL and VISUAL LINE modes. It provides a set of commands for toggling bold, italic, highlight, strikethrough, code blocks, and comments, with the ability to combine or remove formatting cleanly. The plugin integrates well with custom `.vimrc` configurations through the Vimrc Support plugin, allowing precise control via leader-key mappings or ex commands. Even non-Vim users can benefit by binding formatting actions to hotkeys. Designed to solve formatting inconsistencies in Vim mode, it streamlines the editing experience for those who rely on modal workflows.
