The keystroke alias will work if you do this:
alias @@Ctrl-q `echo abc^^^^e[1Ddef`
The ^^^^e will turn into ^^e in the alias definition. Upon executing the alias, the second ^ will be treated as-is and not cause the ^e to act as the <ESC> key and clearing the command line. The remaining ^e will now be treated just as if you had typed it manually on the command line, and cause the ANSI command to work as expected.
