Currently, this is how I do it (on browser version with Chrome):
How to Copy/Paste:
1. Select the target text to copy. Note: the text will not show as highlighted yet, but it is selected
2. Right click in the selected area and choose "Settings"
3. Close the pop-up window. I believe the text should show as highlighted at this point
4. Now you can do the normal Ctrl C and Ctrl V to copy/paste as you normally would in windows
