If you have downloaded and installed the Toolkit, take a look at ''Site.tcl' file.

    if {($::ENV == "dev") && ([info exist ::callback] == 0)} {
	put [tk::help::init]
    }

Above code says that if the environment is "dev", include an online help for the Toolkit as well as your application.

You will get a couple of small icons next to your logo and they allow you to modify and make changes to your application ''from any location'' with an internet access
