Hi Thorsten and list How are you?
small question. ive been using your amazing function daily last few days and been lovin' it :) i wonder if i could request a tiny related feature (this may be very easy to do already). i would like to assign hotkeys for 2 scenarios: 1) pre selected language for 1 line 2) pre selected language prompting for number of lines to wrap so IE id assign F9-b to auto wrap current line with bash syntax while F9-l would wrap in lisp also F10-b would prompt me how man lines to wrap in bash etc is that possible? thanks you again for all your wonderful work kind regards z On Tue, Jul 29, 2014 at 6:36 PM, Thorsten Jolitz <tjol...@gmail.com> wrote: > > Hi List, > > I often missed the following command for wrapping existing content into > src-blocks in the past, besides knowing about > `org-babel-demarcate-block' and easy template insertion.
