Undoing Changes in Visual Mode
After you have made some changes to your screen in Visual mode and updated the file by pressing Enter, you may decide you don’t want those changes after all. You can use the Undo command to cancel these changes.
All of the changes you make on the screen before pressing Enter, are treated by Qedit as one “undo-able” command, except for cut-and-paste operations. Qedit always executes a cut-and-paste last after updating the file with any other changes, no matter what order the changes were made in. This means that you can choose to undo just the cut-and-paste operation, or undo it and all of the other changes. You can continue undoing your previous changes until the file is back to its original state.
