You could try WHEN-NEW-BLOCK-INSTANCE when entering a new block. If you have defined a GLOBAL when you entered the block, you could work out where you have come from. I use this trigger to clear a detail block when the use clicks in a block above it - you can use navigational triggers as I do:
on entry to block S01 - WHEN-NEW-BLOCK-INSTANCE
GO_BLOCK('S02');
CLEAR_BLOCK;
GO_BLOCK('S01');
