Does anyone know how to apply a strikethrough to text in the new Notes app? It seems the option has been removed entirely from all font menus, contextual menus and even the font palette!
Yeah, the option is a bit well hidden, dunno why. Its called Struck through instead of strikethrough
To get the text formatting in Notes 4.0
1) Make a text selection for the struck through, right click on it
2) Select Fonts then Styles
3) Use the Style Browser or whatever that is called to check the Favourite Styles and then select Struck Through from the dropdown list. Tada!
Wow. That was really easy and accessible, right? Why not add another step since all that makes a lot of sense. I guess, this time Apple struck through the UX.
Here one close-up of the option. I think one can make a Keyboard shortcut that will make this more ehh sane to use. Maybe there is one already.
To add on to PJJ's answer, you can more quickly strike through text with the copy style keyboard shortcut. Select some already struck through text, Opt+Cmd+c (Format > Font > Copy Style). Then select the text you want to strike through and Opt+Cmd+v (Format > Font > Paste Style).
The question has probably been answered, but as a side note, there's something nice you can do; assign a keyboard shortcut to strikethrough.
