Description:

This is a most powerful script to let you copy and select without affecting the normal features of each site.

1. disables the .preventDefault() function for 'copy', 'contextmenu', 'select', 'selectstart', 'dragstart', 'beforecopy' events
2. disables the return false in HTML attributes 'oncopy', 'oncontextmenu', 'onselect', 'onselectstart', 'ondragstart', 'onbeforecopy'
3. disables the returnValue in javascript coding for 'copy', 'contextmenu', 'select', 'selectstart', 'dragstart', 'beforecopy' events
4. re-enable "pointer-events" for images
5. de-block alert() for mouse right click
6. css hack to re-enable the selection coloring if transparent coloring is applied
7. disables the .preventDefault() function and "returnValue=false" for 'Ctrl-C' in 'mousedown' & 'mouseup' events if there is text selection
8. allowing the clipboard data replacement in 'copy' events
   • if a non-empty string with text/plain is set.
   • original selection text will be shown in console.log(...) if it is also a non-empty string

Stared Feature: （特色功能:）

1. Enhanced build-in alt text selection - You can now copy the link / button text using Alt-click; the cursor will change from "pointer" to "text", and the selection shall be in pink color.
   （增強內置Alt文字選取 - 針對超鏈結及按鈕文字，按Alt+Click後，鼠標會由"pointer"變成了"text"，並且選取區變成粉紅色。）

known issues:

• this script is intentionally not to disable "return false" in keydown & keyup (Ctrl-C) to avoid performance issue; you should still be able to copy the text using right click.
• "preventDefault()", "returnValue=false", "return false" in mousedown would not be disabled (due to avoid conflict to the normal features)
• not working for <input Value="test" onSelect="blur();">
