  The shifted cursor keys are not available on all terminals.
+ 
+ Another side effect is that a count specified before the "i" or "a" command is
+ ignored.  That is because repeating the effect of the command after CTRL-O is
+ too complicated.

+ An example for using CTRL-G u: >
+ 
+ 	:inoremap <C-H> <C-G>u<C-H>
+ 
+ This redefines the backspace key to start a new undo sequence.  You can now
+ undo the effect of the backspace key, without changing what you typed before
+ that, with CTRL-O u.

Team-building exercises come in many forms but they all trace their roots back
to the prison system.  In your typical team-building exercise the employees
are subjected to a variety of unpleasant situations until they become either a
cohesive team or a ring of car jackers.
