Main Emacs documentation (large): https://www.gnu.org/software/emacs/documentation.html

Vim

Use sed for mass editing of several files: http://sed.sourceforge.net/sed1line.txt (sed commands have close vim parallels)

Use vim with -w and -s options for writeout/scriptin options for complex systematic editing to be mass-performed on many files

Put the following line in your HOME/.vimrc for execution of previous command map V :w^M:!^[OA^M^M " for shortcut V to execute previous command

Put your favorite set into .vimrc.

Write to belur[AT]iitb.ac.in with "Vim help" in the subject for queries.

Old workshop announcement follows below

Please attend any one (or both) of the hands-on workshops on

Emacs
Vim

Any one of these two editors will help you use the full power of shortcuts. (Please use gtypist for a typing tutorial.)

Venue for both workshops: LA 301 (changed)

Date: 21st September (Wednesday), 2016
Time: Emacs: 2:10 to 3:25pm (Note the new modified timings!)
Time: Vim: 4:30 to 5:35pm (Note the new modified timings!)

Both these editors are very powerful and have many advantages compared to most other plain text editors that people tend to use. In fact, many other advanced packages allow you to configure their editors so that your Emacs skills or Vim skills become fully usable.

Both Vim and Emacs are available in both Windows, Linux and Mac.

Speakers:

Jinesh Jacob, Kumar A., Prasad (for Emacs)
Ashwith, Saurabh, Srikant, Prashant (for Vim)
