When a Dump window is open or when a Disassembly window contains storage being dumped, you can change locations by positioning the cursor to the desired area and typing over the contents; you can do this in either the hex or character area of the display.

If the Current Registers window is displayed, you can alter the PSW, general purpose registers, and floating point registers in the same way.

When a Disassembly window is open, you can modify the hex values of the instructions by typing over them. These changes are immediately reflected on the screen with different instruction mnemonics, addresses, and so on.
