If you are using Box Drive as your cloud storage, then you might have experienced if you enter the shortcut Ctrl + Alt + Shift + B, then it would open the Box Search dialog.
This could conflict with some of your other short cut keys. For me it conflicts with Notepad++ XML Formatter shortcut key which I use a lot. In this tutorial I'll show you how to disable this shortcut key. For this you need to have privileges to edit Registry entries in Windows.
1. Navigate to Computer\HKEY_CURRENT_USER\SOFTWARE\Box\Box registry entry
2. Create a new DWORD registry key named GlobalHotKeyCharacter and set the value to 0
3. Restart Box Drive
Now your Ctrl + Alt + Shift + B shortcut would not interfere with your other applications.
Hope this helps.
