6.3.1 Undo and redo in the standard ASCII editor
Function
Edit
When editing a part program or a text file, you can undo complete
blocks in the editor:
• Press "Ctrl" and "Z" for “Undo” (reset)
• Press "Ctrl" and "Y" for "Redo" (reactivate)
Once you undo a series of blocks, you can redo the same number of
blocks. Both functions only apply to programs that are not loaded.
Sequence of operations
"Ctrl" + "Z"
Press the key combination "Ctrl" + "Z". All changes in the entire block
are undone. Repeat the key combination to undo the previous
change. The "CR" symbol at the end of the block is also considered.
This procedure can be repeated until the last change or the set
number of changes has been reached.
"Ctrl" + "Y"
Press the key combination "Ctrl" + "Y".
The last changes undone in the editor are redone. This procedure can
be repeated until the last change is redone or the set number of
maximum changes has been reached.
The default number is 10 steps; this setting can be changed. Setting
the number to zero deactivates the function.
