Testing global shortcuts (accelerators)

My electron app has many webviews and some global keyboard shortcuts like
`cmd=`: zoom in
`cmd-`: zoom out
`cmdr`: reload

Everything works in the app and I want to write integration tests.

Till now I have not found any way to simulate/test this, since, `cmd` key is not identified and thus, nothing happens when I press these combinations.

I have tried RobotJS (does not support latest node version so rebuilding it for electron fails).

No repository file, test, or entry point is named. Start by examining Spectron's existing keyboard-input integration and how Electron webviews handle the listed cmd shortcuts; done would require a documented, working way to simulate and verify those global accelerators.
