So, the whole point of Vim is that it’s supposed to be easy and require as few keystrokes as possible to make stuff happen, right? Well, isn’t it odd that simply saving your work requires double the number of keystrokes that it does in notepad++ or whatever text editor? The nervous tic, the repetitive twitch of the fingers to ctrl+s every few minutes whenever you stop to look over what you’ve typed is universal. So shift + ; and then w and then enter, vs ctrl+s? What’s with that! Weiiiiiiird.
Anyway, here’s a tutorial on how to do a quick key map for ctrl+s http://vim.wikia.com/wiki/Map_Ctrl-S_to_save_current_or_new_files
