Shane – just found this out by accident – instead of hitting TTTT for select all tracks forward tool, you can hit T then shift click the timeline to modify the select track forward tool to act as the select ALL track forward tool. – sweet –
An easier way to select/change all your “A” clips (especially in a long sequence) is to put your playhead at the beginning of the sequence. Hit apple F. Type in the name of your clip and hit find all. This will highlight all your “A” clips in one shot.
