Undo and redo in Microsoft Office

Most programmes offer an undo and redo operation. In Microsoft Office including Word and Excel, the undo will revert your last action. For example, if you have deleted a word accidentally then undo will bring it back. This also works for the previous action and action before that. You can press Ctrl+Z or use the menu in the top left corner for undoing.
There is a special command in Word for repeating and undoing your undone actions which you can access through the buttons in the top left corner or Ctrl+Y. It appears as if that was a two-in-one button. But it basically stores your last action, e.g. typing the word "example", and performs it again.

• example

By using the repeat/redo command, this action will be performed again. Thus, you will see another "example" appearing on screen.

• exampleexample

If you undo this action, the most recent "example" will disappear.

• example

If you repeat/redo your action an additional "example" will appear on screen.

• exampleexample

Location and shape of the buttons

In Word, you have an arrow going backwards for undo (left symbol; Ctrl+Z) and a circle shaped button for redo (right symbol; Ctrl+Y).

The buttons are located on the top left in the newer version of Microsoft Word. The example is from Word 2013.

In the older versions they are integrated in the general menu of symbols, typically in the first row. The example is from Word 2010.

Other issues

In contrast to LibreOffice, you cannot adjust the number of actions in the loop. But you can use the little arrow next to the undo-button and select how many steps you wish to go backwards. You can also press Ctrl+Z until you are where you want to be. Importantly, you can redo your undo if you went to a little far.

The undo and redo in LibreOffice

Most programmes offer an undo and redo operation. In LibreOffice including Writer and Calc, the undo will revert your last action. For example, if you have deleted a word accidentally then undo will bring it back. This also works for the previous action and action before that.
You can press Ctrl+Z or to the menu Edit and click the first entry Undo.
There is a specific way for undoing the undo-command called redo. A special command is required because using undo will go further and further back in the history of your actions. In contrast, redo works in the other direction. For example, you deleted a word and used the undo command. Now, the redo command will delete this word again, i.e. undoing the undo.
You can press Ctrl+Y or to the menu Edit and click the second entry Redo.

Other issues

In LibreOffice, undo and redo are bound to a particular document. That means clicking undo affects the active document, but not any other documents in the background. Limit in number of steps
There is a limit which is typically set to 100. That means you can undo the last 100 actions. In LibreOffice go to the menu Tools → Options... → LibreOffice → Memory. In the top right, you can adjust the number of steps that will be available to you.

Forward button in Google Chrome for Windows

As in every browser you can move forward and backward. This is restricted to the tab that you have opened.
Moving backwards means returning to a page that you have just navigated away from. That means you clicked on some link or typed in another web address and now return to the previous website.
Moving forwards is only applicable after you have navigated backward. For example, you clicked the back arrow once too often. In this case the forward button moves you forward through the pages that you have left. That means, moving forward is undoing your backwards move.

• There is a go forward and a go backward button in the top left corner of the browser. But you can also use keyboard shortcuts.
• Moving forward in history: Alt+Right arrow OR Shift+Backspace
• Moving backward in history: Alt+Left arrow OR Backspace
