Num Lock turns on the number pad. F1 conjures up a Help screen. Ctrl+C copies an item. Windows key+E opens File Explorer.  But you’re not stuck with the existing keys or shortcuts. You can modify many of them with the help of a PowerToys tool called Keyboard Manager.

How to remap keys using Keyboard Manager in Microsoft’s PowerToys

How to remap a shortcut

At the main Keyboard Manager screen, click the entry for Remap a shortcut. Click the dropdown menu to select the physical shortcut or click the Type key to type it. The shortcut must start with a modifier key, meaning Alt, Ctrl, Shift, or Win. After choosing or typing the modifer key, select or type the accompanying key. For example, if you wish to redefine Win+F, choose Win in the first column and F in the second column. For example, you can’t remap Win+L (locks Windows) or Ctrl+Alt+Del (gives you access to Task Manager) as those are reserved shortcuts. But you can remap the function keys F1-F12. If you try to redefine a reserved key in Keyboard Manager, you’ll get a slap on the wrist to prevent you from proceeding. Click the dropdown window and scroll through all the choices until you find the one you want. Alternatively, click the Type button and press the key you wish to redefine. Then click OK to submit it.

Right-click on the shortcut for the app in the Start menu, go to More, and select Open file location. Right-click on the app’s icon in File Explorer and select Properties. The name of the executable file appears in the Target field. Copy and paste or type that filename in the field under Target App. When done, click OK.
