The two commands are "selection to next label" and "selection to previous label".
They have default shortcuts alt+right and alt+left.
A label track does not have to be the focus. If there is a single label track in the project, that it used. If there is more than one label track, then the first label track, if any, starting at the focused track is used.
If the commands are used during playback of the project, playback continues from the new cursor/selection.
The commands provide feedback to screen readers: the name of the label, and position in the form of "i of n".
These are "Moved focused track up/down/to top/to bottom" in keyboard
preferences.
There were prior changes that made any shortcuts for them appear in the track
control drop-down menu, but only after closing Preferences. They still did
not appear after restart of Audacity, although the keystrokes had their effect.

My change here doesn't permit building with gcc 4.8 any more. It would be nicer to do this during configure, but doing it at all may be enough to demote this bug from P1 status.
I also took the opportunity to modifier the Status Bar indications when in the TrackInfo.
1) We now mention ctrl click can select or deselect track.
2) If there is only one track, we don't now prompt about rearranging tracks, since you can't.
3) If you hover in a label track's VRuler (which is just a spacer so that things line up), you now don't get a message.
Progresses us a little towards closing. Ctrl-Click on waveform now removes track selection status, not just adds it, and we don't flicker on again subsequently when we drag. Ctrl-Click won't remove the last remaining selection (by design). Shift-Click can now reduce us down to one track, rather than the previous behaviour when reducing track selection.
Html now uses theming, the dark and text colours and uses waveform colour for hyperlinks.
Previously hard coded white text now uses the theme colour too.
Using panning, we no longer need to distinguish between mono left and mono right tracks. So we do not need to view or set that from the menu. Also split stereo and split stereo to mono are now the same thing. Both split to mono, and both pan the newly created tracks to the extreme.
