Description

The current toast message is currently using Blockly.Msg.COMMAND_KEY which results in "Hold ⌘ Command and use arrow..." which is output by VoiceOver as "Hold command Command and use arrow...". The double "command" is confusing.

Blockly.Msg.COMMAND_KEY = '⌘ Command';

There is a more complex alternative which is that the toasts accept HTML and the symbol can be made aria-hidden.
