Synchronized Output

Synchronized output is merely implementing the feature as inspired by iTerm2 synchronized output, except that it's not using the rare DCS but rather the well known SM ? and RM ?. iTerm2 has now also adopted to use the new syntax instead of using DCS.

Semantics

When rendering the screen of the terminal, the Emulator usually iterates through each visible grid cell and renders its current state. With applications updating the screen a at higher frequency this can cause tearing.

This mode attempts to mitigate that.

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore. The list of supporting software reflects the known state as of this date. ]

---

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

Passive Mouse Tracking

Motivation

While mouse event tracking is already possible in various modes and encodings, this feature seems most used by alt-screen applications however.

The reason why primary screen applications (such as your shell) usually don't make use of the mouse, is the design problem, that whenever the application is requesting mouse tracking events, the user cannot use the mouse to select text on the screen anymore.

With this VT extension, a new mode is introduced to inform the terminal that the user may still use the mouse to select text, but still have mouse events being reported to the application to allow passive tracking of mouse events.
