    this.acels.set('Edit', 'Uppercase', 'CmdOrCtrl+Shift+U', () => { this.cursor.toUpperCase() })
    this.acels.set('Edit', 'Lowercase', 'CmdOrCtrl+Shift+L', () => { this.cursor.toLowerCase() })
    this.acels.set('Edit', 'Drag North', 'Alt+ArrowUp', () => { this.cursor.drag(0, 1) })
    this.acels.set('Edit', 'Drag East', 'Alt+ArrowRight', () => { this.cursor.drag(1, 0) })
    this.acels.set('Edit', 'Drag South', 'Alt+ArrowDown', () => { this.cursor.drag(0, -1) })
