While trying to change the key layout on my computer to make it easier for me while developing I noticed that I couldn’t remap AltGr+G. Google Desktop uses it, as well as Windows+G, as a shortcut to the search textbox. Luckily I found a way to change this behaviour by editing the registry as outlined in this newsgroup thread.

In “HKEY_CURRENT_USER\Software\Google\Google Desktop\Preferences”
create a DWORD value named “hot_key_flags”.
Setting this value to:
– “0” disables both Ctrl-Alt-G and Windows-G
– “1” disables Windows-G, but leaves Ctrl-Alt-G enabled
– “2” disables Ctrl-Alt-G, but leaves Windows-G enabled
– Removing the key or setting the value to “3” or higher will enable
both keys.

So now I can get back to remapping some previously hard to reach keys to more convenient places.
