ultisnip: use <c-l> to avoid breaking vim keys
- don't need i_ctrl-l because we will never set insertmode=1

mimic two emacs movements, other not work because:
- interfere with non-trivial i_ctrl-<key>
- alt-keys (a) differs from platforms, must use ctrl (c)

<c-k> twice for calling func hudigraphs

replace g* and g# because don't use often as g; and g,

note:
- see also :h insert-index
- see also :h map-expression
- '<char> ==> '<char>zz
