screen: Split
9.1 Split
=========
-- Command: split [-v]
('C-a S', 'C-a |')
Split the current region into two new ones. All regions on the
display are resized to make room for the new region. The blank
window is displayed in the new region. The default is to create a
horizontal split, putting the new regions on the top and bottom of
each other. Using '-v' will create a vertical split, causing the
new regions to appear side by side of each other. Use the 'remove'
or the 'only' command to delete regions. Use 'focus' to toggle
between regions.
When a region is split opposite of how it was previously split
(that is, vertical then horizontal or horizontal then vertical), a
new layer is created. The layer is used to group together the
regions that are split the same. Normally, as a user, you should
not see nor have to worry about layers, but they will affect how
some commands ('focus' and 'resize') behave.
With this current implementation of 'screen', scrolling data will
appear much slower in a vertically split region than one that is
not. This should be taken into consideration if you need to use
system commands such as 'cat' or 'tail -f'.
