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.
