I just got this new keyboard working and have been making a few shortcuts triggered by key combinations, like ctrl+Alt+Shift+F12 and the like, and here are a few things I learned that should help everyone doing those kind of things.

1. The key combo you chose for your shortcut WONT work, or won’t be reloaded on next reboot unless it is sitting in specific folders, like the Start menu folder.
2. Shortcuts called with key combinations are unexplicably SLOW to start for some reason. But there is an easy fix to this:

The fix for Custom keyboard shortcuts slowness:

• Open the registry editor Start > Run > Regedit.exe
• navigate to the following key:

HKLM/SYSTEM/CurrentControlSet/Session Manager

• right click and choose: New Value > Dword
• Name the new value “SafeDllSearchMode”
• Set it’s value to 1
• Reboot

This fix should remove most of the lag you experience when executing a custom keyboard shortcut.
