<li> 8. ${lightIcon.replace('width="22" height="22"', 'width="15" height="15"')} 关灯。视频播放时关灯，避免干扰。再次点击该按钮后开灯。</li>
<li> 9. ${autoBackupIcon.replace('width="25" height="25"', 'width="15" height="15"')} 自动备份。每隔2分钟将笔记内容自动备份。点此按钮可展示最近备份的6个笔记。</li>
<li> 9. ${embedModeIcon.replace('width="25" height="25"', 'width="15" height="15"')} 内嵌模式。点击后，左边展示视频，右边展示笔记。可以移动中间分隔线改变两边的占比。再次点击该按钮退出内嵌模式。</li>
<li> 10. Tip1。添加了额外的视频播放暂停/开始<strong>快捷键alt+B</strong>。</li>
<li> 11. Tip2。可以通过拖拽调整笔记大小。</li>
<li> 12. Tip3。可以通过拖拽顶部调整哔记的位置。</li>
<li> 13. Tip4。哔记有wysiwyg(实时预览)和markdown两种模式(可在右下角切换)，但是在实时预览模式下插入时间戳会被强制转义为文本。</li>
<li> 14. Tip5。使用快捷键可帮你更快的记录笔记。</li>
<li> 15. Tip6。文件过大时，保存和导入可能会卡顿。请耐心等待。</li>
<li> 16. Tip7。建议视频播放时启用“关灯”或者“内嵌模式”。这不仅可以减少注意力分散，还可以禁用网页滚动条，便于记录笔记。</li>
