Final answer:
In Code::Blocks, the commands to display various panels can be found under the 'View' menu in the main menu bar, while the 'Tools' menu is for accessing the command line.
Step-by-step explanation:
In Code::Blocks, to find commands that allow you to display various panels, you should navigate to the View menu in the main menu bar. This menu is specifically designed for managing the visibility of panels and toolbars within the Code::Blocks Integrated Development Environment (IDE). While the Tools menu does include options for different purposes such as bringing up the command line, the View menu is where you'll locate options to control the display of various user interface components.
To access the command line panel, as stated in your reference, you would indeed go to the Tools menu and then to the General Controls sub-menu. There, you could use the 'Command: del :.b' or 'Command: focus' to delete buffers or set focus. However, for most panel displays, the View menu is where you would go.
