Quick Access Feature on Toolbar

...  for some reason I was under the impression that there was something like a folder called "Quick Access" that kept these things available without taking up more room on the toolbar.

There was a folder, but it was user set up via the steps Mike described above ... 
You right click on one of the icons you have on the toolbar, then in the dialogue which opens you enter "Quick access" (or whatever you want to call it, such as "Q", etc) into the "folder" input field. Now your toolbar will show this folder on the toolbar. You can then take any of your other shortcut items on the toolbar, right click and repeat the procedure and enter the same folder name in the dialogue. You will notice that the items / icons no longer are on the toolbar itself but they are within that toolbar folder and no longer take up space on your toolbar. A click on the folder shows the list of items in the folder and with a click you open the item.
This procedure can be repeated, and - for example - you could make shortcut folders for "layouts", "commentaries", etc. which you would like to open from the shortcuts toolbar.
