When starting a session to, in my case at least, debian and Ubuntu machines with Putty from a Windows machine, alt-left/right works as moving per word on the command-line. (Often this is also achieved on Linux systems with ctr-left/right).However, once I started using Byobu, and set Byobu to start automatically (using the F9 menu), the alt-left/right doesn't work anymore. Instead when outputting the raw characters using Ctrl-V it shows,  ^[[1;3C-- when sending alt-right. Whereas, when byobu is not started automatically when logging in, but is started manually once logged in, I deduced that it sends, ^[^[[CWhich is caught by a default inputrc config, and consequently it is translated to move by word.What mechanism between Putty, the host/terminal/byobu is in play, to make make this difference in received commands?
When using putty, alt-left/right is different when byobu is started automatically from profile
ssh;terminal;putty;byobu
