Minecraft wiki entry for Sign, associated text: Placing a sign opens an editor interface resembling a magnified view of the sign. Up to four lines of text can then be entered using a keyboard (hardware or on-screen). The editor supports limited editing, including moving the cursor and inserting and deleting characters. Formatting codes can also be used to apply decorative effects such as color, bold, italic, and underline to various bits of the text.‌[Bedrock Edition only] Depending on the edition and platform in use, copy and paste operations may be supported and the editor may also support keyboard entry of Alt-codes for displaying Unicode characters.
