+In some situations, like if you're producing sports, it can be useful to
+skip the preview step and cut directly to a source. Nageru supports this
+through **quick-cut keys**; if enabled, Q, W, E, etc. will have the same
+effect as pressing 1, 2, 3, etc. and then quickly J (for cut). Since it
+is easy to press such a key by mistake, this behavior is off by default,
+and must be enabled explicitly from the Video menu or through the
+“--quick-cut-keys” option.

Channels

The preview and live displays are the most important part of the UI,
-and thus take up the bulk of the space. As you can see, we have only
+and thus take up the bulk of the space. In addition, we have the list
+of channels and scenes (the side-by-side view and the static image)
+along the bottom. As you can see, we have only
one (rather boring) input connected, and it is live. The other input is
disconnected and thus shows only a test color. These correspond to pressing
the 1 and 2 keys on the keyboard to activate preview, respectively—or you can
bland and generic, but it works as a generic pause image when you don't
really want anything on the screen.
+For any given channel, you can see that it is active in the live or preview
+by looking at its border. If it's got a red border, as in the leftmost
+input, it's live (either on its own, or as part of the side-by-side view).
+Similarly, if it's got a green border, as in the second input (you can
+see it if you look closely; it's a somewhat lighter shade of green),
+it will be marked with green. On conflict, red (live) wins, since it is
+the most important piece of information.
+
+If you have many channels, the default single-row view can make for previews
+that are somewhat small. If so, you can switch to the *video grid display*;
