<b>...</b> - delete this!
df>   f< .

:bnext, :bn
:bprev, :bp
:b 3, :b htm[TAB], :b12 (space may be ignored)
Ctrl+^ (6) (toggle between the current and the last used buffer), :b#
:bn, :bd# (switch to next, close previous)
:b#, :bd# (switch to previous, close previous)

:sb#, :sb1, :sbN - split buffer horizontally
:vert sb#, :vert sb1, :vert :sbN - split buffer vertically

--- windows ---

C-W w - move cursor to other window
C-W r - swap 
^w followed by h, j, k or l (ctrl+w, ctrl+H) - move cursor to the left, bottom, top or right window
^w followed by capital H, J, K or L will move the current window to the far left, bottom, top or right respectively like normal cursor navigation.

--- open files ---

vim c:\tmp\test1
ls -la | vim -


:e c:\tmp\test1 (edit existing file or new file)
:sp (split current window in two)
:sp filename
:vsp

--- save and exit ---

:q
:q!

:w
:w filename

:wa (write all changed)

:x is the :wq

:qa, :qa!, :wqa (close all files, tabs, windows)

Never use :x never never never. You'll screw up some day and do :X encrypt your file, and you won't know the key.
