 ### New Features
 
+* Added pinch in and pinch out touch gestures, allowing two-finger pinch gestures to be bound to scripts. (#19938, @kefaslungu)
 * Added the ability to automatically scroll the braille display. (#18573, @nvdaes)
 * After installing or updating NVDA, a dialog now offers options to restart Windows, start the installed copy, or exit the installer. (#19268, #19718, @kefaslungu)
 * NVDA now includes a built-in Magnifier feature that allows you to zoom and magnify parts of the screen. (#19228, @Boumtchack)

@@ -608,6 +608,12 @@ There are 4 possible flick gestures depending on the direction: flick left, flic
 Just like taps, more than one finger can be used to perform the gesture.
 Therefore, gestures such as 2-finger flick up and 4-finger flick left are all possible.
 
+##### Pinch Gestures {#PinchGestures}
+
+Place two fingers on the screen and move them toward each other to perform a pinch in gesture.
+Move them away from each other to perform a pinch out gesture.
+The fingers must move at least 50 pixels closer together or further apart to be recognised as a pinch in or out.
+
 #### Touch Modes {#TouchModes}
 
 As there are many more NVDA commands than possible touch gestures, NVDA has several touch modes you can switch between which make certain subsets of commands available.
