Shortcut: Ctrl+D
Hex insert/delete allows the insertion or removal of characters at the current cursor position while in hex edit mode. This will open a dialog allowing you to choose whether to insert or delete characters, and requires that you enter the number of characters to be inserted or deleted.
If insert is selected, UltraEdit will insert the specified number of characters in the file and initialize them to a hexadecimal value of 20 (ASCII space). The characters may them be modified as required.
If delete is selected, the specified number of characters will be removed from the file beginning at the cursor position.
