Can't send Shift+Tab (it sends Tab) #237

Can't send Shift+Tab (it sends Tab)

s-kotte commented 1 year ago

Can confirm that Shift + Tab does not work with the html5 client. Caps + Tab seems to work. With xpra on a Windows computer shift tab works fine.

xpra version: 4.4.6 html5-client version: 7.0

Tested with Firefox and Chrome, for testing you can use any program e.g. gedit xpra logs:
