[BUG] "alt+-" (Alt Minus) key doesn't work on Firefox (Mac OS)

[rfontoura]

Describe the bug
The "alt + minus" key mapping (neither "-") doesn't work on Firefox, Mac OS.

How are you using react hotkeys components? (HotKeys, GlobalHotKeys, IgnoreKeys etc)
HotKeys

Expected behavior

{
  ZOOM_OUT: ["alt+-", "alt+minus"],
}

The matched function should be called.

Platform (please complete the following information):

• Version 1.1.4
• Browser Firefox 69.0.3 (64-bit)
• OS: Mac OS 10.14.6

It worked when I upgraded to 2.0.0. But now my tests with GlobalHotkeys aren't working. Worked using simple keys (like g) and HotKeys. Tests with hotkeys involving Alt or Command keys are not working.
