I’m a new user, so sorry if this is a basic question. Does anyone know what the standard keyboard navigation controls are to zoom in and out on 3D models. For example using a mouse scrolling in and out will zoom, but I cant find the how to zoom using my keyboard.
Arrow keys = pan
Arrow keys + Ctrl = Grab
Zoom = ?
Usually + and -
Sometimes in combination with other keys but there is no need for other keys here.
This may be true for ArcRotate camera.
For Free camera you actually zoom in moving closer with arrow keys.
As far as I know, there is no specification/standard around accessibility with 3D models (yet). However there have been many discussions, you can start here: Report from W3C Workshop on Inclusive Design for Immersive Web Standards
You can achieve pretty much anything using a keyboard, mouse, generic game controller, XR, camera or microphone.
