1. Spun off  issue 4049 
2. Not sure if this issue will go away after we fix  issue 3696 , so file a
separated one for it

Build: 0.4.154.29 (Official Build 6138)
   OS: Any

Other Browsers:
  Safari: N/A
Firefox3: N/A
     IE7: N/A

Pre-steps:
Add both English keyboard and German keyboard on OS

Steps:
1. Launch English Chrome
2. Switch keyboard to English 
3. Observe the shortcut key for "Debug JavaScript"
4. Switch keyboard to German
5. Observe the shortcut key for "Debug JavaScript" again

Result:
Step3: Shortcut key is Alt+` 
Step5: Shortcut key is Alt+ö

Expected:
We didn't change Chrome UI language, but the shortcut key changes when the
keyboard changed, it might confuse user. Is it better we use some locale
neutralized key and keep it consistent between different keyboards?

Notes:
It also happens when switch keyboard to French, Italian, Spanish, Russian
