How to create toolbar button for Chrome user Tampermonkey script?
I wrote a custom text that I would like to run when I call it (not every time the corresponding web page is loaded). Ideally, I would like to create a toolbar button to run this script. How can I do that?
PS: I need it to run in the same context with web page scripts and be able to call functions built into it.

I don't know exactly which panel you're talking about, but you can add a menu command to the Tampermonkey action menu .
Since your script should work on any page, you need to @include all pages, which can slow down pages with a lot of frames a little.
This script will execute the main function (with a warning statement) only when a menu command is clicked.
// ==UserScript==
// @name Run only on click
// @namespace http://tampermonkey.net/
// @version 0.1
// @description Run only on click
// @include /https?:\/\/*/
// @copyright 2012+, You
// @grant unsafeWindow
// @grant GM_registerMenuCommand
// ==/UserScript==
GM_registerMenuCommand('Run this now', function() {
alert("Put script main function here");
}, 'r');
Page functions can be accessed in two ways:
function main () {
window.function_at_the_page();
}
var script = document.createElement('script');
script.appendChild(document.createTextNode('('+ main +')();'));
(document.body || document.head || document.documentElement).appendChild(script);
or simply:
unsafeWindow.function_at_the_page();
