F1 Help

The help feature opens a web page with help corresponding to a symbol under the keyboard cursor. If help URL cannot be determined, informational message box is displayed instead.

The help is opened by pressing F1 while keyboard cursor is placed within a word of interest, inside the word, at its begining or end.

By default, the help works for standard PHP functions, constants, classes, interfaces and most of keywords. Moreover, the help works for class and interface members (class functions, properties and class constants), if editor is able to recognize the member's class name.

In addition, help also looks at user defined functions, classes and constants. In case their PHPDoc contains @link tag with URL, the URL is opened.

Note: @link tag is supported since version 1.18. Prior to this version, message box with failure is displayed instead.
