The <commandTips> element can be used to translate text-command strings into another language.
Text-command strings are used to explain commands to the user. Each one consists of a message that is displayed in the status bar of the program. There also is a tip that is displayed in a popup tool-tip whenever the user hovers their mouse over the command.
Here is an example from MyCommandTipSkin.xml:
<?xml version="1.0" encoding="UTF-8"?>
<manifest name="My Command Tip Skin" author="Me" type="Language" language="en"/>
To create a translation skin, copy the existing command tip database from default-en.xml in your skins folder and start translating each entry.
