Many commands in Word have keyboard shortcuts assigned to them, making it quicker to apply formatting, save the file, and perform other tasks on your documents. These keyboard shortcuts can be customized, and you can assign shortcuts to commands that do not currently have them.
in word 2013, how can one customize the keyboard shortcut for a new, custom ribbon tab?
Some commands I am not able to change, such as Control+Alt+S, which does a tablesplittcells. I would like it to be removed, but there is no option, in order to type the letter ß. which shares the shame command.
