There is, unfortunately, no shortcut key available to toggle between showing and hiding files or folder in the File Explorer. Hence this [AutoHotKey](https://www.autohotkey.com/) script. You can toggle the view in File Explorer to show or hide with the just a `Win+h` shortcut key. 

This script is not that fancy, it just toggles between two different values of the specific registry key and will send `F5` keystroke to refresh the view in File Explorer.

```text
SetTitleMatchMode, 2
#IfWinActive ahk_class CabinetWClass
#h::
  RegRead, HiddenRegValue, HKEY_CURRENT_USER, Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced, Hidden

  if HiddenRegValue = 2 
    RegWrite, REG_DWORD, HKEY_CURRENT_USER, Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced, Hidden, 1
  Else
    RegWrite, REG_DWORD, HKEY_CURRENT_USER, Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced, Hidden, 2

  WinGetClass, CabinetWClass
  Send {F5}
  return
#If
```

If you don't prefer the above script, you can still toggle hidden items with the combination of multiple keystrokes in File Explorer. The key combination is `Alt+v hh`.
