 ### Key Mappings
 - Leader key: `<Space>`
 - Save: `<leader>s`
-- Buffer delete: `<leader>q`
+- Smart buffer delete: `<leader>q` (switches to next buffer, or opens explorer if last buffer)
 - Quit: `<leader>qq` (force quit: `<leader>qqq`)
 - Format code: `<leader>ff`
 - Toggle comment: `mm` (normal/visual mode)
+- Show diagnostics: `<leader>d` (uses Snacks picker)
