Now in that same vein, you can still to that based on something called A-Master Page. So if we come up here to the Pages Palette in the upper ride-hand side of the screen, you can see it is divided into two sections. We have our main document pages here at the bottom and we have what we call the Master Pages at the top. Now, the first Master Page here in defined by a letter. An alphabetical letter which is what is usually used to define it from all the other Master Pages that we may create and this letter A is actually showing up on all these other pages showing that they are defined or created from whatever this Master Page contains.
Well, at the moment, we have made something called a local overwrite on a couple of these first pages. We change the columns and gutters manually, so even if we went into here, I made a change now to the master column guide settings, it will not affect these pages that we have applied into separately. So, we will give this a quick try, all we have to do is come up here to the Master Page icon and select either one by double clicking it and that will take us into the A-Master spread. Now, we can see that because it is highlighted here in black in the Pages Palette, but also, just to show you how to double check it in the very lower left hand side of the document, you can see here it says A-Master. There is a small pop-up menu there that gives us access to any of the pages in the document. We can jump very quickly to any of them by choosing one or straight back to the Masters. So do check that we are inside the A-Master.
Come back up to the Pages Palette again and hold down the shift key and make sure that the right Master Page icon is also selected. Because as you know already, if we have only one selected, any changes we made to the layout margins and columns will only affect that single one. So, if we have them both selected, we can affect them both at the same time. So, come back up to the layout menu once more. Go down and choose Margins and Columns. This time, we will just change it from three columns up to four on both pages. We can see it happening there in the background. Click OK and just scroll across. We can see that all four columns have been applied to both of them. But, if we come back to the Pages Palette now and select either page four or five, it does not matter. Just double click one of them to take you from the Master Page into that page. We can see that both pages four and five contained the four column guides because these pages have not been affected manually. These are still controlled by the A-Master Page. So, if we wanted to, we could jump back to page one. We can see that there is no column. Page two has the original three. Page three has just two columns. Pages four and five have four columns each. And these are all done very easily by affecting things manually or automatically inside of InDesign.
Now, one thing we can do as well is simply press CONTROL Z to undo the last command which actually removes those four columns from the Master Page and if we go back to pages four and five now, we can see that those have returned back to the three column layout. And the important thing there is that the COMMAND Z function or CONTROL Z on the PC is to undo and that will undo as many times as you want to. You can go as far back inside the program as you need to inside InDesign because there are multiple undos. Now, if you do happen to undo two far, you can simply hit COMMAND SHIFT Z or CONTROL SHIFT Z on the PC and that will redo any steps that you accidentally went to far back on. So, do bear that one in mind to get a little bit trigger-happy with the undo command. That is something that also helps us in this situation as when we select an individual page let us maybe jump across the page two again by double clicking its icon. It always centers our preview on that page that we selected.
There is a keyboard shortcut that allows us to view the entire spread in the window and that is simply CONTROL ALT 0 or COMMAND OPTION 0 on the Mac and that will view both pages together. Now, it is possible to do multiple-page spread inside of InDesign, maybe you have three or four pages that are all going to fold into one. If you did have one of those set-up and you use the same command, you would see all four pages together. If they are connected inside the Pages Palette, InDesign will preview them all as one spread. So, do bear that one in mind if we are jumping back and forth and you wish to see how an entire spread looks. In seeing as most of our design layout we are going to do for this training is based on a double-page spread of the brochure. This is very much the one that you want to remember.
