Action(key-in) for "Toolboxes" window.

To open the Toolboxes window, I have to do "File-------->Settings---------> [Toolboxes] button.

But I would like to have a key-in to use an action in a Function key.

If I use the key-in, there is the key-in: DIALOG TOOLBOX + (ANY TOOLBOX).

Maybe, it would be interesting another one: DIALOG TOOLBOXES       (or TOOLBOXES DIALOG) to open directly the toolboxes window.

If we custom the Quick Acces Toolbar by button it is "Tool Boxes"
