This is EXTREMLY easy to do and doesn't require a keyboard to do. All you have to do is go to type in your clan tag, find the Greek looking letter and type this letter "" followed by any other button. It will look like A for the A button in your clan tag. Here is a list of all the buttons you can do:


A= A button
B= B button
C= X button
D= Y button
E= LB button
F= RP button
N= Start button
O= Back button
P= LS button
Q= RS button
R= LT button
S= RT button
T= Up arrow button
U= Down arrow button
V= Left arrow button
W= Right arrow button

Enjoy and please thank and rep<3
