That makes a lot of sense... The way I have implemented the
<S-F1>-<S-F4> keys is to ask the user to initialize a variable,
g:Tex_HotKeyMappings, which defaults to

g:Tex_HotKeyMappings =
	\ 'eqnarray*,eqnarray,bmatrix'

(The default was chosen on a whim. Note bmatrix is an amsmath
environment.)
With this default, only <S-F1> through <S-F3> are mapped. Putting one
more item in the list will map <S-F4>... Since this variable is set
during the initialization, it will be somewhat tricky to use the
knowledge of \usepackage{amsmath}... By tricky, I dont mean coding as
much as how to document and approach this feature...

Should we have two variables

g:Tex_HotKeyMappings_amslatex = 'equation,equation*,align,align*'
g:Tex_HotKeyMappings_latex = 'equation,\[,eqnarray,eqnarray*'

and then use one or the other? But I am thinking that since we want to
encourage the user to customize latex-suite anyway, is there a reason to
have this intelligence at all? Most users will I think either use
amsmath all the time or never... So they could just tailor the setting
once and forget about it...

Also, is there any reason, why you always don't use the multiline
versions. If you want to do just one equation, you could just choose not
to insert another \\ and an equation. This way, we could two of those
keys for something else...

Thats an interesting idea... As of now, <S-F5> recognizes the
environment the user is in and asks him to choose which new environment
to change it to (from a list)... Maybe we can have a command which
instead of asking just cycles through a few possibilities? That might be
faster in some cases...

Also, from now on, with latex-suite introducing so many mappings, it
might be a good idea to only provide commands as Luc suggests and let
the user choose a mapping for it if he wants to use the feature...
