Typing accents and symbols depends on the platform you're using. For more information see here: http://sites.psu.edu/symbolcodes/

Windows

On Windows 11, the shortcut Windows key + . (period) will bring up the "Emoji and more" popup, where you can select the symbols category for punctuation and more.

You can also use Windows' system Character Map utility and select the accented characters to copy and paste into your Fade In document.

Alternately, you can use predefined key combinations such as Ctrl+' then the E key to type "é", or you can type character codes directly using Alt+0nnn, where nnn is the numeric code as per http://sites.psu.edu/symbolcodes/windows/codealt/.

See Microsoft's Keyboard Shortcuts For International Characters for more details. (Note that not all key combinations may be supported by Fade In, and/or some combinations may conflict with default or user-defined shortcut keys.)

Mac

Holding down a regular letter key will bring up a list of any accented variations on that letter.

You can also use the Keyboard and Character Viewer from Language & Text preferences to find the accented characters you want. You can alternately type the characters directly using the Option+ key combination for a particular character. Note that some accents are produced using a two-keystroke combination. For instance, to type an "ñ", you would first type Option+N (to indicate a tilde ("~"), then N again.  To type "õ", you would type Option+N, then O.To type "é", first type Option+E (for "´"), then E.

Linux

Depending on your distribution, you may have a character map or equivalent utility, that you can use to find and copy/paste the desired characters into your Fade In document. Depending on your keyboard layout, you may be able to use some Windows-style predefined key combinations, as indicated above, and/or you may be able to use Compose key (sometimes called AltGr) combinations as described here.
