In French (as well as in several other languages), curly apostrophes ( ’ ) are preferred to the straight ones. Microsoft Word can automatically convert straight apostrophes into their curly version, via its AutoFormat As You Type function. Unfortunately, many translation tools with a dedicated environment will not perform such conversion, even when they have a similar setting as in Microsoft Word, as is the case in memoQ.
This video shows how to modify an existing keyboard layout using the Microsoft Keyboard Layout Creator, a free utility that works with all versions of Windows from XP to 10. On the modified layout, the straight apostrophe is replaced by its curly version, while the straight apostrophe is added to the same key, when used with the Ctrl key.
The modified layout is then added to the active keyboard via Control Panel.
The same technique can be used to modify any other key(s) on the keyboard layout.
