Move
the Color and Borders Palettes
While working on an Excel worksheet, you might want to colour a few
of the cells, change the font colour for the text, or add borders
to a range of cells. To add colour, you select a cell, click on the
dropdown arrow at the right side of the colour button on the toolbar,
and click on a colour.

That’s simple enough, but all those trips up and down from the toolbar
can get a bit tiring, and take extra time.
