Explorer looks in 4 places for hotkeys, these are read on startup. The hotkey is stored in the shortcut. Only hotkeys on shortcuts in the four locations are live.
Type in a command prompt
cd %UserProfile%\desktop
for %A in (*.lnk) do findhotkey.vbs "%1"
for %A in (*.pif) do findhotkey.vbs "%1"
for %A in (*.url) do findhotkey.vbs "%1"
cd %AllUsersProfile%\desktop
for %A in (*.lnk) do findhotkey.vbs "%1"
for %A in (*.pif) do findhotkey.vbs "%1"
for %A in (*.url) do findhotkey.vbs "%1"
cd %UserProfile%\Start Menu
for /r %A in (*.lnk) do findhotkey.vbs "%1"
for /r %A in (*.pif) do findhotkey.vbs "%1"
for /r %A in (*.url) do findhotkey.vbs "%1"
cd %AllUsersProfile%\Start Menu
for /r %A in (*.lnk) do findhotkey.vbs "%1"
for /r %A in (*.pif) do findhotkey.vbs "%1"
for /r %A in (*.url) do findhotkey.vbs "%1"
Each shortcut, that has a hotkey, will pop up a dialog with the name of the shortcut and it's hotkey.
You may have path problems. To make it work put in c:\ and change
for %A in (*.url) do c:\findhotkey.vbs "%1"
as all these directory changes may make it difficult for the script to be found (but shorten the amount of typing for the start menu FORs).
Ctrl + C Copies the text of a message box to the clipboard.
It is not reccommended that Ctrl + Alt be used with Hotkeys. Ctrl + left hand side Alt = Right hand side Alt (marked Alt Gr on keyboards for international use - keyboards only differ with what is painted on the keys) and enters international characters if using the US International keyboard (a driver that knows what is painted on the keys so you get the right character).
