How to fix randomly slow shortcut keys

From my post on microsoft.public.windowsxp.general:

Problem: I have an icon on the desktop which is a shortcut to the .EXE of a file manager application. That icon has a shortcut key to it, Ctrl+Alt+N. I extremely often switch to this application, so I press the shortcut key maybe once every minute or two throughout the entire working day.

The problem is that often, Windows will NOT switch to the application when I press the keyboard shortcut, but very slowly, only after perhaps half a minute.

Solution: The best solution that was found so far is to apply this registry patch: fix slow hotkeys:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager]
