... many details will need further work, but basic navigation among
pushbuttons with control-alt-arrows and presses with control-alt-space will
work.
Shift-ctrl-alt-down on track panel works to navigate among individual tracks,
and shift-ctrl-alt-up to escape back to the higher level.
Enh1444 is to make pinch and spread gestures work.
Bug1435 is to bring focus rings back for types of controls that lost them in
version 2.1.2. This importantly includes pushbuttons and choice controls
(drop-down menus). Less importantly, date picker (as in the Timer Record
dialog) and Listbox (as in the dialog to choose label font).
There is one more type of control that lost focus rings, and is not fixed:
List controls (distinct from list boxes), such as in the Manage Curves dialog
that opens from Equalization.
