In merge editor, I cannot access the result editor via command/keyboard

[meganrogge]

1. Open the merge editor
2. Navigate to the result editor via keyboard 🐛 not possible

Henning mentioned that we could have a command that lets you toggle between the editors, which would accomplish this.

Meanwhile, a workaround could be to enable: vscode://settings/git.mergeEditor to "Open the merge editor for files that are currently under conflict", and then use this keyboar shortcut:

{
  "key": "ctrl+1",
  "command": "workbench.action.focusFirstEditorGroup"
}
