Often times, when I run a vim command that makes “big” changes to a file (a macro or a :vimgrep command) I lose my original position and feel disoriented.

Save position with winsaveview()!

The winsaveview() command returns a Dictionary that contains information about the view of the current window. This includes the cursor line number, cursor coloumn, the top most line in the window and a couple of other values, none of which concern us.

Before running our command (one that jumps around the buffer, a lot), we save our view, and restore it once its done, with winrestview.

let view = winsaveview()
s/\s\+$//gc              " find and (confirm) replace trailing blanks
winrestview(view)        " restore our original view!

It might seem a little overkill in the above example, just use “ (double backticks) instead, but it comes in handy when you run your file through heavier filtering.

1. reselecting previously selected text (i use this to fix botched selections):

   gv  " :h gv for more
       " you can use `o` in visual mode to go to the `Other` end of the selection
       " use a motion to fix the selection
   

2. reselecting previously yanked text:

   `[v`]
   `[         " marks the beginning of the previously yanked text   :h `[
   `]         " marks the end                                       :h `]
    v         " visual select everything in between
   
   nnoremap gb `[v`]    " "a quick map to perform the above
   

3. pasting and indenting text (in one go):

   ]p   " put (p) and adjust indent to current line
   ]P   " put the text before the cursor (P) and adjust indent to current line
