Use Undo and Redo

In IBM 3270 Mainframe and 5250 iSeries, BlueZone users can undo and redo actions related to the following: mouse cursor movement, emulation cursor and field functions, Edit, Cut and Paste, and user text typing. BlueZone stores up to 32 of the supported actions.

Undo and redo can be accessed through the BlueZone menu bar, under Edit → Undo or Edit → Redo. In addition, Undo and Redo icons can be added to the BlueZone toolbar.

Refer to IBM 3270 and 5250 toolbars for more information.

Use the Undo command

When a user invokes one of the supported functions mentioned above, the Undo function turns from gray to normal. Also, the Undo function label changes to the last supported function.

For example, if you enter some text on the screen, the Undo function changes to Undo Typing. If you move the cursor to a new location, the Undo function changes to Undo Move Cursor and so on. If you perform many of the above supported functions, the Undo function can undo each item in reverse order.

Use the Redo command

Redo is the opposite of Undo. For example, if you used the Cut function to remove text from a field, and after the text was cut, you thought you made a mistake so you used the Undo function to put the text back. But then you realized that you did not make a mistake after all, you can use the Redo function to Redo the original Cut function which results in the text being removed form the screen.
