Easy shortcut key in Nemo

I tried for a long time to do this, and Gemini came up with a way-easy way. 

 Method 1: Hover and Press (The GTK Way)

GNOME and Cinnamon have a built-in feature where you can assign a hotkey just by hovering over a menu item.

1. Open Nemo and right-click a folder to open the context menu.
2. Hover your mouse cursor directly over Open Folder in qView (do not click it).
3. While your mouse is hovering over the option, press your desired keyboard shortcut (e.g., Ctrl+Shift+Q).
4. Look closely at the text. The shortcut should instantly appear right next to the name in the menu.

Note: If pressing the keys does nothing, open your terminal and run gsettings set org.cinnamon.desktop.interface gtk-menu-shadows true or check if editable-menu-accels is enabled in your system settings, as some modern themes block live menu editing.

 It appears to end up in two places: .config/nemo/actions-tree.json and accels

    {
      "uuid": "qview.nemo_action",
      "type": "action",
      "user-label": null,
      "user-icon": null,
      "accelerator": "<Alt><Super>q"
    }, 

and

(gtk_accel_path "<Actions>/NemoActions/context/qview" "<Super><Mod1>q")
