To ignore white spaces while using vimdiff.
From the command line use:
vimdiff -c 'set diffopt+=iwhite' ...
To have vimdiff ignore whitespace while normal vim doesn’t, simply put this into your .vimrc:
" diff mode"
In command mode press the keys
ga (like get ascii) or :as / :ascii on the command line to find out the ascii code of the character where the cursor is. This displays the value of the current character in decimal, hex and octal. (Think “get ascii.”)
To do a search and replace with an hex code
Being 0d the ascii character found with ga
Seeing ASCII/Unicode values in the status line
You can also add options to the statusline option to show the ASCII/Unicode value of the character under the cursor.
:set statusline=%<%f%h%m%r%=%b\ 0x%B\ \ %l,%c%V\ %P
It’s the %b\ 0x%B that does the trick. Note that you may need to :set laststatus=2 so that the status line is visible in with only one window showing.

Vim mailing list says (re-formatted for better readability):
To change two vertically split
windows to horizonally split
Ctrl-W t Ctrl-W K
Horizontally to vertically:
Ctrl-W t Ctrl-W H
Ctrl-W t makes the first (topleft) window current
Ctrl-W K moves the current window to full-width at the very top
Ctrl-W H moves the current window to full-height at far left
Note that the t is lowercase, and the K and H are uppercase.
Also, with only two windows, it seems like you can drop the
Ctrl-W t part because if you’re already in one of only two windows, what’s the point of making it current?
