Introduction
Jupyter Notebook is an interactive notebook program with rich shortcut keys to easily complete work. Notebook has two keyboard input modes. That is, command mode and edit mode, which are somewhat similar to Vim . In edit mode, you can type code or text into the cell. At this time, the cell is surrounded by a green frame, and the shortcut keys in command mode do not take effect. In command mode, you can use shortcut keys to run cells, move cells, switch the editing state of cells, etc. At this time, the cells are surrounded by a gray frame, and the shortcut keys in editing mode do not take effect.
