Select and Use the Current Viewport
When you use multiple viewports, one of them is the current viewport, which
accepts cursor input and view commands.
When a viewport is current, the cursor is displayed as crosshairs rather than
an arrow, and the viewport boundary is highlighted. You can change the
current viewport at any time except when a View command is in progress.
To make a viewport the current viewport, you click inside it or press Ctrl+R
to cycle through the existing viewports.
To draw a line using two model space viewports, you start the line in the
current viewport, make another viewport current by clicking within it, and
then specify the endpoint of the line in the second viewport. In a large
drawing, you can use this method to draw a line from a detail in one corner
to a detail in a distant corner.
