showing discontinuous files in corkboard

Hi all – I would like to show selected non-contiguous files in the corkboard, say the 1st, 2nd, and 5th file within a folder. I can select the 1st and 2nd just fine, but if I hold the shift key down and then click on the 5th file (skipping 3 & 4), it selects and shows everything above it, rather than only the 3 files I want.

What am I doing wrong?

Hold CMD key not the SHIFT key.

Thanks so much for the help!
