Use Outline on a Mac and an iPad Pro to do creative writing which as you might imagine entails instances of often daily or even hour to hour revision. Do not see a keyboard key for a text strikeout or strikethru (and vice versa, of course). If it aleady exists, can you locate it for me. If it doesn't, can you consider adding it, say, next to the (on my MacBook) three keys that already exist for Bold, Italics and Underline (on the OSX version). At the moment, I find myself using either the underline feature to cue me to what I want to creatively revise or consider for creative revision OR I use a different font/text color OR I use a highlighing color EACH of which strategies work but not the way a simpe strikethru would to focus the writer on moments of writing that should be considered as candidates for rethinking, reworking, or ultimate deletion. Thank you.
