[BUG] callback gets call incorrectly with incorrect key

[aprilmintacpineda]

Describe the bug

The callback gets called incorrectly on mac.

Example code

keyboardJS.bind('c', () => console.log('c called!'));

• When I press c, it gets called, which is correct.
• When I press shift + c, it gets called, which is incorrect.
• When I press command + c, it gets called, which is incorrect.

Here: https://jsfiddle.net/p7Lbz9uh/

Expected behavior

• When I press shift + c, the callback should not be called.
• When I press command + c, the callback should not be called.

Enviroment (please include the following info):

• OS: macOS
• Browser: Chrome@latest
• Version: Not sure what to put here.

Additional context

When I do:

keyboardJS.bind('c', () => console.log('c got called!'));
keyboardJS.bind('command + c', () => console.log('command + c got called!'));

The correct callback gets called, but shift + c will still say c got called!, but when I do:

keyboardJS.bind('c', () => console.log('c got called!'));
keyboardJS.bind('command + c', () => console.log('command + c got called!'));
keyboardJS.bind('shift + c', () => console.log('shift + c got called!'));
