Don t press Esc ever  See this answer to learn why  As mentioned above  Ctrl   C is a better alternative  I strongly suggest mapping your Caps Lock key to escape  If you re editing a Ctags compatible language  using a tags file and  ta  Ctrl      etc  is a great way to navigate the code  even across multiple files  Also  Ctrl   N and Ctrl   P completion using the tags file is a great way to cut down on keystrokes  If you re editing a line that is wrapped because it s wider than your buffer  you can move up down using gk and gj  Try to focus on effective use of the motion commands before you learn bad habits  Things like using  dt  or  d3w  instead of pressing x a bunch of times  Basically  any time that you find yourself pressing the same key repeatedly  there s probably a better faster more concise way of accomplishing the same thing

The most recent  wow  trick that I learnt is a method of doing complicated search-and-replace   Quite often in the past  I ve had a really complicated regexp to do substitutions on and it s not worked   There is a better way    set incsearch               I have this in  vimrc  my complicated regexp       Highlighted as you enter characters   s  replace with this       You don t have to type it again   The  trick  here  for want of a better word  is the way that you can use the search to create the regexp  and  incsearch  highlights it as you enter characters  and then use an empty pattern in the substitution  the empty pattern defaults to the last search pattern   Example    blue   d       s  red 1    Equivalent to     s blue   d     red 1    See    help  incsearch   help  substitute

I just discovered this one while browsing the Vim help    help index   This takes you to a single  searchable   page with all the commands for all the modes   So if you know that the command you re trying to remember learn starts with or involves a certain keystroke  you can search for that and flip through all the possibilities  Or you can just browse the mode you re interested in to see learn editing possibilities   I can t count the number of times I ve done just  help Ctrl   R or whatever and gotten just the first thing  which is of course never the one you want  This is much better than  helpgrep IMO   And into the  vimrc it goes   nnoremap  lt silent gt   lt F1 gt   help normal-index lt CR gt  inoremap  lt silent gt   lt F1 gt   lt C-O gt  help insert-index lt CR gt     help still gets you to the default F1 page
