How to you place a caret over the letter "i" in the words "maitre de"?
You don't. You put a circumflex accent.
The keyboard shortcuts for the French accents are very simple. Type
Ctrl- and the closest-looking punctuation mark, and then the letter it
applies to.
For circumflex, it's Ctrl-Shift-^
For acute, it's Ctrl-apostrophe
For grave, it's Ctrl-`
For tilde, it's Ctrl-Shift-
For cedilla, it's Ctrl-comma
For dieresis, it's Ctrl-Shift-colon
