Select all in VIM editor

The simplest and fastest way is to use: : % y + and then go over to Google Docs (or wherever) and paste. Explanation:
  • % to refer the next command to work on all the lines
  • y  to yank those lines
  • +  to copy to the system clipboard
Another way is g g " + y G but you will likely admit that the above is faster and easier.
