KB shortcut to toggle Filters, CTRL-SHIFT-L is not working

[Jeffrey Green]

If i have A B C D in columns 1,2,3 and 4 respectively, then press CTRL SHIFT L, Excel swaps columns 1 and 2, with 3 and 4!!!

Leaving me with C D A B . . . and i can't even UNDO IT!

My coworker is fine.

Excel 2013, all files, even after a reboot.

Thoughts?

solved! I had a SORT ROW Macro and years ago i set the keyboard short cut to CTRL-SHIFT-L!!!! If i put A B C D, nothing happened, but if i put D C B A, then Excel sorted them back to A B C D!
