A 3D document editing system and graphical user interface (GUI) that includes a virtual reality and/or augmented reality device and an input device (e.g., keyboard) that implements sensing technology for detecting gestures by a user. Using the system, portions of a document can be placed at or moved to various Z-depths in a 3D virtual space provided by the VR device to provide 3D effects in the document. The sensing technology may allow the user to make gestures while entering text via a keypad, thus allowing the user to specify 3D effects in the document while typing. The system may also monitor entries made using the keypad, apply rules to the entries to detect particular types of entries such as URLs, and automatically shift the detected types of entries forward or backward on the Z axis relative to the rest of the content in the document.
