You can also quickly go to a specific cell address in a worksheet using the Go To... feature. Press Ctrl+G (or select Edit -> Go To...). Type the cell address you want to go to into the Reference box, and then click the OK button:
The Go To... feature keeps a list of cells that you have recently moved to using the Go To... feature. To quickly move to a particular cell in the Go To... list, double-click that cell address.
To move even faster than Go To..., to a specific cell on a worksheet, type the cell's address (the column letter and row number; for example, C25) into the Name box at the left end of the Formula bar and press Enter.
