Disclaimer.
ConEmu is not a shell, so it does not provide "shell features" like tab-completion, command history and others. But you can run any shell or remote access client of your choice in ConEmu! Try Clink for bash-style completion in cmd.exe and PSReadLine or PowerTab in powershell.exe. Or just run Bash from your favourite distro.
Also, ConEmu does not provide remote access (SSH/Telnet/...) too, just use your remote client (ssh.exe, telnet.exe) instead.
