// Module Name:

// - Pane.h
|
|
//
|
|
// Abstract:
|
|
// - Panes are an abstraction by which the terminal can dislay multiple terminal
|
|
// instances simultaneously in a single terminal window. While tabs allow for
|
|
// a single terminal window to have many terminal sessions running
|
|
// simultaneously within a single window, only one tab can be visible at a
|
|
// time. Panes, on the other hand, allow a user to have many different
|
|
// terminal sessions visible to the user within the context of a single window
|
|
// at the same time. This can enable greater productivity from the user, as
|
|
// they can see the output of one terminal window while working in another.
|
|
// - See doc/cascadia/Panes.md for a detailed description.
