When a single command string is provided, returns True or False to indicate whether a button running the specified command would appear enabled or not.

Example:

if (IsEnabled("Set VIEW=thumbnails")) { ... } // Is thumbnails mode available?

If two or more commands are provided, returns 0 if no commands are enabled, otherwise returns the index of the first enabled command.

By default the test is applied to the source file display, but you can prefix the command you're testing with left:, right:, dest: or both: to test conditions in specific file displays.

Example:

viewMode = IsEnabled("Set VIEW=thumbnails", "Set VIEW=details");
// viewMode will equal 0, 1 or 2 depending on what view modes are available
