I am connecting from a windows machine to a remote machine using MobaXterm,  and attach to a tmux session. Some key are not getting sent correctly, for example prefix + arrow keys just prints {A,B,C,D} when I press prefix+{up,down,right,left}, when these keys should navigate between tmux panes. If I use Putty (instead of MobaXterm), I can fix this by using 'linux' terminal instead of 'xterm', but in MobaXterm the terminal types I can choose are xterm, xterm-r6, vt100, vt220, and vt900. None of them work.I guess some of the problem is the remote machine itself (which runs Ubuntu 16.04), because other remote machines do not have this problem.Any suggestions?
