Include shortkeys that match with Hydra?

[tmhglnd]

Hey,

Not sure if this is desirable, because it will break how things previously were. But would it be good to have the shortkeys for Hydra match with the hydra website?

This could be included in the TextEditor.tsx

if (target === 'hydra') {
  defaultExtraKeys = {
    ...{
      'Ctrl-Enter': () => this.evaluateLine(false),
      'Alt-Enter': () => this.evaluateBlock(false),
      'Shift-Ctrl-Enter': () => this.evaluateAll(false),
    },
  };
}

Or I think at least we should include the shortkey for evaluateAll()
