Command Line
From FirebugWiki
The small Command Line supports auto-completion using the Tab key. For example, typing 'w' followed by Tab repeatedly will cycle through all global variables starting with the letter 'w'. Since Firebug 1.6 there's also an popup with suggestions shown for the entered part of a command.
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 ( 
).

Features
Auto-Completion
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. If there are several commands starting with the same phrase like "getElem" then pressing tab several times alphabetically switches 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.
