What does "rnds" mean in the middle of pattern instructions?

This is a shawl pattern with brioche stitch and these are the instructions in one part:

Brioche part
Short row 7 (rs): k1, p1, k1, kbYOf, k1, sl1YO for 6 sts,
k1, turn work,
mds, brk, SL1YO, repeat to 6 sts bef end, k1, SL1YO, k1,
p1, k1, p1. (2 incr’d sts)
Short row 8 (rs): k1, p1, k1, kbYOf, brk, sl1YO, repeat
to ds, kds, sl1YO, k1 for 8 sts, turn work,
mds, brk, sl1YO, repeat to 6 sts bef end, k1, sl1YO, k1,
p1, k1, p1. (2 incr’d sts)

What does the "rnds" or "mds" mean in the middle of the short row after turning the work? I've searched high and low and can't figure it out. I assume it has something to do with the short rows? It is not in the instructions what this stands for.

thanks, Angela
