How to swap windows using JIS keyboard I have got a JIS keyboard layout recently, I always swap between windows using command + ` , now I have no idea how to do it.
Here is the layouts of two found on the internet.

JIS and US keyboard layout
Is one of the keys on the right side of the keyboard (like ろ or ￥) maybe backtick? 

If not, you can remap some key to backtick with KeyRemap4MacBook. Save a file like this as ~/Library/Application Support/KeyRemap4MacBook/private.xml:

&lt;?xml version="1.0"?&gt;
&lt;root&gt;
  &lt;item&gt;
    &lt;name&gt;test&lt;/name&gt;
    &lt;identifier&gt;test&lt;/identifier&gt;
    &lt;autogen&gt;__KeyToKey__ KeyCode::JIS_UNDERSCORE, KeyCode::BACKQUOTE&lt;/autogen&gt;
    &lt;autogen&gt;__KeyToKey__ KeyCode::JIS_YEN, KeyCode::BACKQUOTE&lt;/autogen&gt;
  &lt;/item&gt;
&lt;/root&gt;


Then open the KeyRemap4MacBook application, press the ReloadXML button, and tick the checkbox for the setting.

The shortcut for moving focus to the next window can also be changed from System Preferences:
