Connecting to byobu in Ubuntu 16.04.3 LTS on a Windows 10 system, when I type Shift+F2 to get a vertical split, nothing happens. Typing plain F2 works and opens a new window. Ctrl + F2 works too and splits vertically.
I tried all the terminal keyboard types in PuTTY/Kitty/ConEmu configuration (ex. XTerm R2, Linux) without any luck. Any ideas? Is there any another keyboard shortcut to do the same thing?
