New page (screen) can be cut on frames either horizontally or vertically. And each of received frames can be also divided into two frames either horizontally or vertically. There are two ways to do it:

1. Click on the frame you want to split with your left mouse button. Go to the Main menu to FRAME => "Split frame vertically" or "Split frame horizontally".

Click by right mouse button on frame area you want to split and select "Split frame vertically" or "Split frame horizontally" in the shortcut menu.
