-Removing `-` from this list will allow it to be used while generating citation keys.
+<!-- issues https://github.com/JabRef/jabref/issues/6295 and https://github.com/JabRef/jabref/issues/4709 -->
+Since JabRef 6.0, the default unwanted characters are `?`, `!`, `;`, `^`, `ʹ`, and backtick (&grave;).
+If you also want to have `-` be removed (e.g., "Al-Ketan, 2019" should be "AlK19" instead of "Al-19" when using `[auth3][shortyear]`, add `-` to this list.
+
+Note that [characters not allowed in BibTeX](https://tex.stackexchange.com/a/408548/9075) are completely removed - independent of this configuraiton.
+These characters are `{`, `}`, `(`, `)`, `,`, `=`, `\`, `"`, `#`, `%`, `~`', and `'`.
