For some time I have used tabstop=4 in my source files. Now that I write lot of javascript that has deep indentations, a tabstop of 4 seems wasteful, so I want to convert it to 2. The problem is I use "set expandtab" too. So merely setting tabstop=2, won't help.
Any suggestions on how I can convert all my files quickly to tabstop 2?
My current relevant .vimrc settings are
set tabstop=4
set shiftwidth=4
set expandtab
