Current behavior

The enter icon (⌤) in the HotkeysHelpComponent is not recognized by our users.

Expected behavior

It would be nice if the icon is changed if the Device is not a Apple-Device
or if we can configure the icon
or if it is replaced by just 'enter'

Minimal reproduction of the problem with instructions

open the HotkeysHelpComponent when a shortcut with 'enter' is added.
