::: Important Notes

On Mac systems, use the option key instead of the alt key used in Windows/Linux.
Some shortcuts may conflict with system shortcuts and need to be changed in system settings.
Math formula-related shortcuts must be used in the corresponding math input environment.
Table and matrix operation shortcuts only work in their corresponding environments.
It is recommended to memorize commonly used shortcuts to improve editing efficiency.
Paragraph first-line indentation, right alignment, center alignment, and left alignment shortcuts currently only support Windows. :::
