# Changing data

When a window of data displays, it is followed by an equal
sign. Pressing CTRL+N displays the next window (if available) and
CTRL+P displays the previous one.

New data can be entered as:

| .hex | Hexadecimal string insertion. The hexadecimal string is preceded by a period. It must contain only hexadecimal characters and an even number of nibbles. The characters in the display window are replaced by those in the input string, beginning from the left. |
| --- | --- |
| {+\|-}int | Integer insertion. The display window is treated as a numerical element. The window must be 1, 2, or 4 bytes long. The new integer replaces all data in the window. |
| 'char | Character insertion. The character string is preceded by a single quotation mark. The characters in the display window are replaced by those in the input string, beginning from the left. |
