Eclipse and many other popular IDEs come equipped with a helpful feature known as "code assist," which suggests various possibilities with the press of a hot key (such as ctrl+space
), a specific event (like pressing <
), or after a certain timeout period (most of which can be customized).
Aptana Studio is an IDE based on Eclipse, designed specifically for web development.
If you prefer an "auto-complete" functionality akin to Firebug in your IDE rather than just suggestions, you can adjust the settings to achieve a similar result (such as enabling "completion overwrites" instead of "completion inserts" for Eclipse).
