Hi Ken, Thanks for your comments. Currently, we've no plans to change the navigation commands. With the current set-up, you can simply navigate with mouse, or when using tablet with finger or stylus without needing any keyboard controls. So, all navigation commands are easily accessible and easy to use. Of course, we are also looking for ways to improve Tekla BIMsight based on our customers needs. So, we'd like to know, are you missing for Tekla Web Viewer's "Fly" functionality, or some shortcuts to perform certain navigation actions? Thanks, Heikki
