How do you type an accent above a letter, such as cu?
The easiest way is to set it up on your keyboard. If you are on a windows PC go into Settings, Time and Language, Language, Options, Add Keyboard, and then add Scottish Gaelic.
Then if you click ENG on the bottom right of your windows screen it'll give you the option to swap. The shortcut for writing a grave accent above a vowel is to hit the apostrophe button followed by a vowel. à è ì ò ù
