Shift combinations not working

That usually happen when ya get crumbs under the Shift key on ya keyboard....use some compressed air to blow out.

try the other shift key

is it the same?

move temporarily--flash drive if its big enough--second internal drive if you have one--dvd if its big enough

make a second partition on your hard drive and move it there

upload it to a file storage service--unless its too much data

My keyboard is clean and the other shift has the same problem

Same

And damn, forgot about partitions, thanks.
