When it comes to translating computer-related text, Microsoft glossary is indispensable. I always refer to MS glossary while translating computer-related materials. Microsoft glossary can be found at the Microsoft Language Portal.
The following is a simple AutoHotkey script which enables me to search Microsoft Glossary with ease. (You must have AutoHotkey installed on your system.)
For example, highlighting a word or string and then pressing [Ctrl+Shift+W] can be changed will open the Microsoft Glossary page with search results. (You can change the shortcut easily.) The above script will search a Korean glossary. Please change it according to your language.
Note: If the script above does not work, please try it after specifying Google Chrome as the default browser.
