There is no current function of choosing to show labels (in a temporal
fashion) for the current selection. However, there are new tools in QGIS
2.0 to help show only the labels you want. Depending upon your desired
workflow, consider using 'Show Label' data defined option (under Vector
Layer Properties Dialog -> Labels -> Rendering section). You can map an
attribute field for your layer, or define an expression.

[Show Label data definition description]
  Expected input:    bool [1=True|0=False]
  Valid input types:  string, int, double

If not using an expression, but instead mapping an attribute field, you can
then either edit the attribute table accordingly (e.g. create a selection
and update existing field values using the Attribute Table Editor), use the
Show/Hide Label tool, or toggle the check box in the Change Label
Properties dialog.

Manipulating the attribute table allows for different expressions to be
applied, while the Show/Hide Label allows you to interactively work with
the labels on the map canvas:

[Show/Hide Labels tool tip]
  Click or marquee on feature to show label
  Shift+click or marquee on label to hide it
  Acts on currently active editable layer
