Dom Perignon is like Formula 1.
It is suitable to compare chord mappings optimized for a common but very small subset of keystrokes (space and letters with a tiny smattering of upper case and punctuation).
My daily keyflow contains stuff like this
if (mrOk == NForms::ShowAddVariable(GetDocumentPtr(), GetSelectedObjectKey(), eOperatorType, strName, &poOperator)) {
And an awful lot of this
<Down><Down><Ctrl><Right><Right><Right><Right></Ctrl><Ctrl><Shift><Right></Shift></Ctrl><Ctrl><Left><Left>cfv</Ctrl><Enter><Ctrl><Home></Ctrl>F3F3F3F3<Esc>
thumbless, the mapping I use, is more of a 4 Finger Drive.
