In JavaScript we quite often use strings as some kind of identifiers. Event and module names are good examples here.

A good IDE should support this in my opinion. With this plugin you can define a format of your identifiers. Each JavaScript string matching this format becomes a 'symbol' which you can rename(Shift + F6), find usages of (Alt + F7) or Go To (CTRL + Click).

By default all strings in format ':hyphen-identifier' are symbols but you can configure recognized formats in the plugin configuration page.

You can find this plugin on IntelliJ plugin repository. Take a look at IntelliJ IDEA documentation for instructions about installing plugins.

After installing, this plugin will recognize 'symbols' and will highlight them blue:

Symbols which appear only once in whole project are marked with warning:

Referenced symbols are shown without warning:

Symbol names will appear in the suggestions list (Ctrl + Space Bar):

You can easily find usages of symbol with Alt + F7:

Even more conveniently you can go to usage with Ctrl + left click:

Last but not least you can rename your symbol with Shift + F6:

You can configure recognized symbol formats in Other Settings -> JavaScript Symbols.

This plugin is definitely not finished. If you've found it useful feel free to contribute.
