How to disable Tab Focus for Button

[jsprog]

Goal
For an app depending heavily on keyboard hot-keys, It's more convenient to disable the Tab-Focus for some targets, while keeping the Tab-Focus restricted only to some targets (e.g: search-field + few other buttons)

The Problem
I'm forced to use the Standard Button to keep all the inherited styles intact, while disabling Tab-Focus for some Buttons

FocusScope itself has a focus-on-click and focus-on-tab-navigation property, but these are not forwared by the widgets at the moment.

Ideally it would be done as part of something like that: #81
We'd need a way to describe the order of widgets in the tab focus chain, and exclude some of them.
