I found that Format Painter shortcut Ctrl+Shift+C and Ctrl+Shift+V in Word 2019 is no longer working. As a predominantly keyboard shortcut user I found this incredibly frustrating and could not find any answers that worked. I finally found a solution that fixed it for me after being pointed in a certain direction from another post but was vague enough I had to figure it out on my own further. I thought I would post the below in the hope that it may help others to find the solution quicker, as a lot of the same question threads have been locked with out a satisfactory solution:
I found that Word had changed the Format Painter shortcuts:
CopyFormat: From Ctrl+Shift+C to Alt+Ctrl+C; and
PasteFormat: From Ctrl+Shift+V to Alt+Ctrl+V.
If, like me, you don't want to learn the new shortcuts and prefer the previous shortcuts, go to the menu File | Options | Customize Ribbon:
Select the 'Customize' button for Keyboard shortcuts at the bottom of the pop-up box.
Under the column Categories, select 'All Commands'.
(for the copy formatting shortcut)
In the right column select 'CopyFormat'.
Under 'Current keys' select the Alt+Ctrl+C and select 'Remove'.
Under 'Press new shortcut key' enter Ctrl+Shift+C
Select 'Normal' to Save changes in.
Select 'Assign'.
(for the paste formatting shortcut)
In the right column select 'PasteFormat'.
Under 'Current keys' select the Alt+Ctrl+V and select 'Remove'.
Under 'Press new shortcut key' enter Ctrl+Shift+V
Select 'Normal' to Save changes in.
Select 'Assign'.
