To view a repertoire of all characters, choose Insert - Special Character.
In the large selection field double-click on the desired character, which is inserted in the current document.
In any text input field (such as the input fields in the Find & Replace dialog) you can press Shift+CommandCtrl+S to open the Special Characters dialog.
On Windows: To insert a character using its numeric code, press and hold down Alt while typing the numbers on the numeric keypad. Code starting with 0 is interpreted as Unicode character; otherwise, below 256 is interpreted in Windows codepage.
At present on Unix systems, there are three ways of entering letters with accents directly from the keyboard.
Solaris: Using a Sun keyboard. First press the Compose key to the right of the space bar, then enter the first and second modifiers.
Linux / NetBSD: Using the dead-keys. In an xterm window first press the (´) or (`) key. The character should not appear on the screen. Now press a letter, such as "e". The e is given an accent, é or è. If not, then check in the XF86Config file if a "nodeadkeys" XkbdVariant has been loaded there and replace it. You may also have set the environment variable SAL_NO_DEADKEYS, which deactivates the dead-keys.
All Unix systems: (Alt Graph) as additional compose key. The (Alt Graph) key can work in LibreOffice like the Compose key, if you set the environment variable SAL_ALTGR_COMPOSE. The (Alt Graph) key must trigger a mode_switch, so, for example, xmodmap -e "keysym Alt_R = Mode_switch" must be set. First press (Alt Graph), then the first modifier, then the second modifier. The characters are combined as described on a Solaris system in the file /usr/openwin/include/X11/Suncompose.h.
