    same as :gmli[st]!

=== gmload ===
:gmlo[ad] {name|filename}:
    load the user script to the current page

    Caution:
        This change is permanent, not only the session.
        And cannot get back.

    :gmset! {filename} -n fooScriptName -i http://*,https://* -e http://example.com/*:

        when any URL and scriptName.user.js is executing


== Dialog ==

:dialog userscriptmanager:
    open Greasemonkey UserScript Manager

liberator.plugins.gmperator:
    allItem:

            return the current {GmContainer} object
        currentSandbox    :
            return the current sandbox object
