The Command Bar allows you to access almost all of the Codio actions from a searchable list. You can also use it to look up keyboard shortcuts. You simply start typing and the list is refined as you type.
Use one of the following methods to invoke the Command Bar:
Click Tools on the menu bar and choose Command Bar.
Press Cmd+Shift+P (Mac) or Ctrl+Shift+P (PC/Linux) on the keyboard.
