In macOS, you can split the Terminal screen into multiple panes using the “Split Pane” feature.

Here’s how you can do it:

Open Terminal: Launch the Terminal application on your macOS.

Split Pane Horizontally: To split the Terminal screen horizontally into two panes, press the following key combination:
Command + D

This will split the current pane horizontally, creating a new pane below the current one.

Split Pane Vertically: To split the Terminal screen vertically into two panes, press the following key combination:
Command + Shift + D

This will split the current pane vertically, creating a new pane beside the current one.

Navigate Between Panes: To move the focus between different panes, you can use the following key combinations:

Horizontal Split:

Move to the pane above: Control + Option + Up Arrow
Move to the pane below: Control + Option + Down Arrow

Vertical Split:

Move to the pane on the left: Control + Option + Left Arrow
Move to the pane on the right: Control + Option + Right Arrow

Unsplit Panes: If you want to unsplit the panes and revert to a single pane, you can use the following key combination:
Command + Shift + D

This will close the current pane and merge it back into the remaining pane.

By using these key combinations, you can split and unsplit the Terminal screen as needed, allowing you to work on multiple tasks simultaneously or view different outputs side by side.
