Active-cell is a term used in Microsoft Excel to describe the currently selected cell in a spreadsheet. However, there are several synonyms for active-cell that can be used interchangeably, such as current-cell, selected-cell, highlighted-cell, and focused-cell. These terms all refer to the same concept of indicating which cell in the Excel spreadsheet is currently being worked on or edited. The use of these synonyms can help to avoid repetition or confusion when discussing Excel spreadsheets with others. It's important to note that the active-cell can also refer to a cell that contains a formula or function that is currently being edited.
