All user actions in JupyterLab are processed through a centralized command system. These commands are shared and used throughout JupyterLab (menu bar, context menus, keyboard shortcuts, etc.). The command palette provides a keyboard-driven way to search for and run JupyterLab commands:
The command palette can be accessed from the View menu or using the keyboard shortcut
Command/Ctrl Shift C.
The command palette can be displayed in the sidebar by adding
'modal': false to the Settings.
