Key too ambiguous. Settled on KeyCode. (Partialy because eventually I want to intro a class named Key). * KeyEventArgs improvements. cast to Rune must be explicit as it's lossy * Fixed warnings * Renamed KeyEventArgs to Key... progress on fixing broken stuff that resulted * Fix ConsoleKeyMapping bugs. * Fix NetDriver issue from converting a lower case to a upper case. * Started migration to Key from KeyCode - e.g. made HotKeys all consistent. * Fixed build warnings * Added key defns to Key * KeyBindings now uses Key vs. KeyCode * Verified by tweaking UICatalog * Fixed treeview test ... again * Renamed ProcessKeyDown/Up to NewKeyDown/Up and OnKeyPressed to OnProcessKeyDown to make things more clear * Added test AllViews_KeyDown_All_EventsFire unit tests and fixed a few Views that were wrong * fixed stupid KeyUp event bug * If key not handled, return false for datefield * dotnet test --no-restore --verbosity diag * dotnet test --blame * run tests on windows * Fix TestVKPacket unit test and move it to ConsoleKeyMappingTests.cs file. * Remove unnecessary commented code. * Tweaked unit tests and removed Key.BareKey * Fixed little details and updated api docs * updated api docs * AddKeyBindingsForHotKey: KeyCode->Key * Cleaned up more old KeyCode usages.
