Ah, I see what you mean.  I think one of the strongest points of Vim
is that there is a fairly standard key map that people generally don't
deviate from.  For example, I type Dvorak and have only changed the
home row movement keys jkhl to htjk.  h and t for up and down, j and k
for left and right.  Vial currently supports this kind of remapping
(the same as Vim's :map command), so that you can map any single
keypress to any other single keypress, or in fact a single keypress to
multiple keypresses, ie "D" -> "dd" perhaps.
I think this level of remapping is probably sufficient.  The
DEFINE-PATTERN macro is not really meant to be used by end users, only
for adding the default mappings.
Does that make sense?
