Hello. If I have a long DNA sequence and I want to reverse it to read right
to left instead of it reading left to right, does anyone know how to do this
the easy way without having to retype everything manually?

For example, if I have:
Abcdefghijklmnopqrstuvwxyz

I want:
zyxwvutsrqponmlkjihgfedcba

Does anyone know the shortcut or the function? Thanks a lot.
