electron 中 nls.localize({ key: ‘miUndo’, comment: [‘&& denotes a mnemonic’] 这种”&&”是什么用处？

if (isMacintosh) { undo = this.createDevToolsAwareMenuItem(nls.localize({ key: 'miUndo', comment: ['&& denotes a mnemonic'] }, "&&Undo"), 'undo', devTools => devTools.undo()); redo = this.createDevToolsAwareMenuItem(nls.localize({ key: 'miRedo', comment: ['&& denotes a mnemonic'] }, "&&Redo"), 'redo', devTools => devTools.redo()); cut = this.createRoleMenuItem(nls.localize({ key: 'miCut', comment: ['&& denotes a mnemonic'] }, "Cu&&t"), 'editor.action.clipboardCutAction', 'cut'); copy = this.createRoleMenuItem(nls.localize({ key: 'miCopy', comment: ['&& denotes a mnemonic'] }, "&&Copy"), 'editor.action.clipboardCopyAction', 'copy'); paste = this.createRoleMenuItem(nls.localize({ key: 'miPaste', comment: ['&& denotes a mnemonic'] }, "&&Paste"), 'editor.action.clipboardPasteAction', 'paste'); } else { undo = this.createMenuItem(nls.localize({ key: 'miUndo', comment: ['&& denotes a mnemonic'] }, "&&Undo"), 'undo'); redo = this.createMenuItem(nls.localize({ key: 'miRedo', comment: ['&& denotes a mnemonic'] }, "&&Redo"), 'redo'); cut = this.createMenuItem(nls.localize({ key: 'miCut', comment: ['&& denotes a mnemonic'] }, "Cu&&t"), 'editor.action.clipboardCutAction'); copy = this.createMenuItem(nls.localize({ key: 'miCopy', comment: ['&& denotes a mnemonic'] }, "&&Copy"), 'editor.action.clipboardCopyAction'); paste = this.createMenuItem(nls.localize({ key: 'miPaste', comment: ['&& denotes a mnemonic'] }, "&&Paste"), 'editor.action.clipboardPasteAction'); } 比如这里很多 &&，到底啥意思？
