So in COTW there's no rebind key for ";" or the "L", "R" bumpers in a controller.
As a result you might find yourself in a struggle..
"How can I select multiple replays for deletion?"
"How am i supposed to switch difficulty in EOST mode?"

You have a keyboard in a non English language!
Go to the windows language bar and switch to US English.
Then try your keyboard in notepad to identify the ";" key.
Usually it should appear on the "ñ" key.
That's it! now in game you will be able to do all the things that were once forbidden..

Another option would be to plug a controller... However this workaround was made of people like me who are keyboard fighters.

For some reason COTW won't take an input if it requires [Shift] or [Alt GR] which is common in non US Keyboards.
