In my iMac 21.5-inch computer (OS X El Capitan Version 10.11.1) I have a cordless keyboard.
At the top of the key 6 I have ˆ instead of ^.
This is a problem. I never have needed to use ˆ, however ^ I need to use it very often. For example, formatting formulas at Math Stack Exchange with MathJax.
Therefore I need to look it up in the Internet.
Is there a special shortcut for having an input of ^? Or is there a way to change my keyboard inputs?
