I ended up with a keyboard piece scored ONLY in 1 clef. It is mostly notes lower than e above middle c but should still be in 2 clefs.
I can not find a way to get it into 2 clefs. I started a new pice with 2 keyboard clefs and copied the old pice into it. It showed up in only the bass clef. I tried to copy the upper 4 notes or so with cntrl x and place them in the treble clef but apparently that's not allowed. I can not select just the top 4 out of 5 notes. It just jumps down and copies all of them.
The other way is to change where musescore splits the clefs (I think) but I don't know how to do that.
help and thanks
