The Command Line appears along the bottom of the Console Panel (small)
Small Command Line‎
or as Command Editor in the Side Panel on the right (large)
Large Command Line (Command Editor)
. The red arrow in the lower right corner toggles between small and large.

The small Command Line supports auto-completion using the Tab key. For example, typing 'w' followed by Tab completes it into 'window'. Cycling through the possible completions is done with the arrow keys. Since Firebug 1.6 there's also an popup with suggestions shown for the entered part of a command, unless disabled in the Console options.

In general the Command Line evaluates whatever expression you type in. It can be a single variable or a complete JavaScript program. The evaluation is done by passing the Command Line text into the page, calling eval() on it and passing back the result.

The Command Line also supports the Command Line API, a set of special purpose commands.

In Firebug 1.6 the Command Line was made available to all panels (called Command Line Popup) and can be accessed through the Command Line Popup Button ( CommandLinePopupButton.png ). To see the output of the commands you have to drag the resizer above the Command Line Popup.

Features

Auto-Completion

Small Command Line‎

To support the user analysing elements and writing code the small Command Line integrates an auto-completion for the commands you are typing. Therefore after starting to type a command you simply have to press Tab and Firebug is completing the command. It is also possible to complete a value with Enter or the Right arrow key or by clicking an item inside the Completion List Popup. If there are several commands starting with the same phrase like "getElem" you can use the Up and Down arrow keys before pressing Tab to alphabetically switch through all available commands. Thereby also the global variables, which you defined in your script, are used.

Clipboard functionality

The entered script can be copied as bookmarklet via the menu of the Command Editor.

Shortcuts for inspected elements

The Command Line and the Command Editor offer you the possibility to easily access elements inside the DOM similar to the sizzle selector library integrated in the jQuery Framework. For a detailed description of the available commands see the Command Line API.

Inspect object in other panel

How you inspect elements using the console is described above. Besides that it's also possible to inspect them in the most appropriate panel by hitting Shift+Enter instead of just Enter. The console output also often contains links to other panels like the DOM Panel.

Inside the Console Panel the Command Line has some additional features.

Command History

The Command Line saves all executed commands in a history. You can go through that history by simply pressing Up and Down. The complete history of all the executed commands is available via CommandHistoryButton.png.
