Are command-line editing interface on topic? [duplicate]

Question

Using emacs in shell is activated by default or by the following command:

set -o emacs

Are the questions about the shell commands on topic?

Example 1 (see comments): how to achieve some text conversion results using emacs mode, instead of using vi.

Answer 1

This falls under the topic of emacs key bindings in an another application, in this case the bash shell. As discussed in Are questions about getting emacs-like behavior in other things on topic?, such questions are off topic on this site.
