For VR Tourviewer version 1.2.303 a bug has been reported with the VR keyboard that appears when adding an online tour. The Shift and Caps-Lock button don't display the 'Shift' characters on the keyboard.
The correct characters do appear in the text field when a key is pressed, but currently you can't see which Shift characters are in which place. So if you first press Shift and then press 'a' an 'A' will appear in the text field.
To find the correct key you can use the image below for the layout of the keyboard when Shift is pressed.
Edit 2020-01-20: This issue is fixed in version 1.2.304(https://www.vrtourviewer.com/images/VRTV-Keyboard-layout.jpg)
This issue has been fixed in version 1.2.304 - now available for Oculus Go, Gear VR, Quest, Rift and Google Cardboard.
