This recent question:
How to distinguish C-m from RETURN?
Actually describes the same problem as these two questions:
How to distinguish C-i from TAB?
How to bind C-i as different from TAB?
In both cases users are experiencing the same root problem but coming from a question regarding different symptoms, some have problems with C-i and others have problems with C-m.
My initial thought would be to close the recent question in as a duplicate, but I also want people searching for C-m issues to have as nice a landing page as people searching for C-i issues.
Is this a scenario where having duplicates is better than closing a question as a duplicate? Or should these not actually be considered duplicates?
