Currently the "history" command in Cmder prints commands without any index associated with any command, so you can copy/paste a command or use "!!" to execute a command from the history but, unlike BASH, you can't do "!<command_index>".
"cat" has a switch, "-n", which prints line numbers of the file being printed. This, in conjunction with "history_io=3" in Clink settings (to read/write history when editing a command") works just like BASH, i.e., you can use the index printed next to a command in the history to execute that command as "!<command_index>".
