Motivation:
1. The text boxes in the label track are not fully accessible for users of screen readers, and I don't think that they can be made to be fully accessible using the accessibility API used by wxWidgets. When such an edit box becomes the focus, this is not announced, and for NVDA users typed characters are not echoed.
2. Provides a work around for bugs 1778 (cannot type diacritics into text label), and 1804 (Windows: Labels do not accept IME (Chinese/Japanese) input).
Fix: Provide an option for a dialog for entering the name. The text box in the dialog is accessible for screen readers. On windows the text box receives wm_keydown and wm_char messages and so is a work around for bug 1804. Being a standard text box, it will presumably be a work around for bug 1778.
1. There is a new option in track behaviors: "Use dialog for the name of new label", which is off by default.
2. When using the commands "Add label at selection" and "Add label at playback position", when the dialog closes, focus is returned to the track which was the focus before the dialog opened. I think this is more convenient for users of screen readers.
The old method was overly reliant on absolute value.
Now we have penalties base on consecutive samples signs.
We'll only make a change if the overall score is good enough.
Also we try to avoid making a point selection, if we were not previously a point.
When these commands were initially written, they operated on the focused track. This is no longer the case, so I've remove the requirement for the TrackPanel to be the focus.
Previously the ID for a macro was, e.g. Macro003. However this would
not work if macros were added or deleted, since chains containing the old
macro references would now refer to a different macro. So changed to using
names.
Done by giving Macros... dialog an Expand / Shrink button
so that we can use it as just an apply-to-projects dialog, if we want.
The dialog is modal, and can be kept open whilst we work. So for example
we could put useful presets into it as macros.
- Remove menu-version of effects. They are already there because of EffectsManager.
-- This gets rid of all the entries with long paths in them.
- Mark more menu items as prompting, using '...', and so not suitable for chains.
- Changes, mostly to capitalization, per https://wiki.audacityteam.org/wiki/Wording
- Removed some dead comments.
- Added a very few i18n-hints
- Per consensus, removed ':' in some strings read by screen readers.
