Hi here, I want to have the feature of (Un)comment a line or several lines with markers at an arbitrary position(s) in/spanning this/these line(s). Say in the following example, `|` indicates the markers:
\usepackage|[T1]{fontenc} \usepackage[utf8]{inputenc}| `C-c ;` gives the following: \usepackage% [T1]{fontenc} % \usepackage[utf8]{inputenc} `C-c %` gives the following: \usepackage[T1]{fontenc} % \usepackage[utf8]{inputenc} But the desired result is something as follows: % \usepackage[T1]{fontenc} % % \usepackage[utf8]{inputenc} Any tips will be appreciated.
