In Microsoft PowerPoint, the Ctrl+D shortcut key inserts a duplicate of the selected slide. Using the Ctrl+R shortcut will fill a row instead of a column. Highlighting the cells in Microsoft Excel also fills all highlighted cells. However, in Google Sheets you must highlight the first cell and all cells below it to fill and then press Ctrl+D. In Microsoft Excel, pressing Ctrl+D in a cell with text in the cell directly above it will fill the cell. Google Sheets and Microsoft Excel both share this shortcut but have slightly different steps. Then press Ctrl+D to fill them with the contents of the original cell. To fill more than one cell, select the source cell and press Ctrl+Shift+Down to select all cells. In Microsoft Excel and Google Sheets, pressing Ctrl+D fills the cell beneath with the contents of the selected cell in a column. For example, you can press Ctrl+D now to bookmark this page.
All major Internet browsers (e.g., Chrome, Edge, Firefox, Opera) pressing Ctrl+D bookmarks the current page or add it to favorites. On Apple computer keyboards, the Ctrl key is labeled as "control.". To use the keyboard shortcut Ctrl+D, press and hold either Ctrl key on the keyboard and while continuing to hold, press the "D" key with either hand. For example, in most Internet browsers, Ctrl+D is used to add the current site to a bookmark or favorite.
Alternatively referred to as Control D and C-d, Ctrl+D is a shortcut key that varies depending on the program.
