In this video, I'm going to share some keyboard shortcuts that you can use to quickly shift between views in the comp panel. The first setting is the Magnification setting in the lower left corner. Obviously, you can click on the pull-downs and make adjustments accordingly, but sometimes it's quicker just use key commands. The first command that I use quite often is Shift+Forward Slash key. It looks like the Question Mark key. That'll automatically resize the window. So no matter what size I move my panels around, it'll go ahead and increase or decrease the magnification to give me the maximum view possible.
Now, the next variation on that, I just use the Forward Slash key to quickly toggle to 100% magnification. This way, I can quickly double-check the sharpness or clarity of whatever it is I'm working on. Now, in conjunction with changing the magnification, sometimes I like to be able to change the resolution. That's this pull-down right here. Now, most of the time I have it set to Auto. That way, when we zoom in and out, it'll change its resolution. So instead of snapping to 100% Magnification or Fit to Window, you can just step through Magnifications using the Comma key and the Period key.
Now notice when I set my resolution to Automatic, it's automatically updating as I change my Magnification settings. Now, what if I just want to change my resolution settings independent of my magnification settings, and I want to do that using keyboard shortcuts. Well, that's when the Command+J or Control+J commands come in. So if you're on Windows, you can use the Control versions instead of when I say Command. The way we layer these is like this. Command+J will automatically set at full resolution. So Control+J on Windows.
If you add a Shift to that equation, so Command+Shift+J or Control+Shift+J, that will set it half resolution. And then if you add the Option key or the Alt key on Windows, then press J, that will set it at one quarter resolution. Let's just press Command+J or Control+J to get back up to 100% resolution. Now, the last thing I like to be able to adjust in the Comp view very quickly is the ability to view the different channels. To give you a better example of that, let's go to the energize type composition.
In here I have a graphic with an Alpha channel. Now quickly, I'll press my Forward Slash button to make sure that I'm viewing at 100% magnification. Now to quickly go between channels, I'm going to hold the Option key on the Mac. It's Alt on Windows and then you can press 1, 2, 3, and 4 to step through each of the different channels, red, green, blue, and the Alpha channel. Now, if you prefer to actually look at the color channels with the color overlay, you can press Shift+Option or Shift+Alt, and then it's 1, 2, 3, and 4. Now, if you press 4 again, while holding Shift+Alt or Shift+Option, it'll toggle between the straight overlay and just the normal RGB view. With the straight overlay, you can see any of the straight channels, all applied one on top of each other.
And since this graphic was rendered with a straight Alpha channel, I have that little bit of overprint that's going on on the edges of the word. So I'm going to hold Shift+Option, Shift+Alt on Windows, and press 4 to toggle between those views. Now that's just a quick tour of some of the comp view shortcut keys that I like to use as I'm working in After Effects.
