This is probably a combination that NONE searches whatsoever except when they are so bored to death that they feel like buying a rope, and you have with almost 100% certanity already searched qwertyuiopasdfghjklzxcvbnm, qazwxedcrfvtgbyhnujmikolp, qetuoadgjlxvnmbczkhfspiyrw, qwertyuioplkjhgfdsazxcvbnm, poiuytrewqasdfghjklmnbvcxz and many more.

This beautiful combination of letters is made by alternating between typing the first and last letters on the keyboard, while also skipping every other letter, and when your hands reach the middle of the keyboard you need to do some hand yoga to keep going past each other until all letters have been used.

Needs lot's of practise and there is a great risk of making a knot out of your hands, and raging over one letter that you typed wrong, so this is reserved for only the most bored people in existance. If you read this, you are one of them.

Congratulations.
