Menu: Window > Split Vertical
Default Shortcut Key: none
Macro function: SplitVertical()
The Split Vertical command can be used to split the current window vertically. A split window provides a second view into the same file, allowing two different sections of the file to be viewed simultaneously in different window panes. Each window pane can be scrolled separately from the other, just as if a second window were in use.
After a window is split, a thin splitter bar appears which visually separates the two panes. The splitter bar can be dragged left or right with the left mouse button to resize the window panes.
Clicking on the splitter bar with the right mouse button provides access to its context menu. The context menu has options to change the split from vertical to horizontal, or to turn off the vertical split so the window becomes whole again.
When the width of the window is increased or decreased due to window resizing, the relative position of the window split will be maintained, so long as each pane remains wider than the minimum window width.
If the Column Ruler is in use, it will appear in both the left and right window panes of a vertically split window.
