1. Minus sign: -strike-through text-
   • easy to remember
   • some chance to break existing text
2. Tilde: ~strike-through text~
   • easy to remember
   • less chance to break existing text
3. Hash: #strike-through text#
   • dash and tildes have the opposite intended visual effect when in edit mode -- they make the in-between text stronger and more apparent.
   • possible conflicts with anchors and numbered headings and lists.
4. (add yours)

Also remember that there is another shorthand candidate for the tilde, see EasierNop

I'm not a strong proponent of # for strike-through. I added it for completeness because it came up in another syntax discussion (which I can't locate at the moment found it! see below). I find using <s> is pretty simple and straightforward.

Since I'm druthering, it would be nice to have some similar simple markup for struck out text. "=" would be the first thought I'd have there, but that's an obvious conflict with TWiki's monospace markup.

With regard to strike-outs, I've thought something ##like this## might work. (dashes and similar looking characters have the opposite effect of making the supposed-to-be-deleted text look more pominent instead of less). I've always thought it strange, and silly, that <strike> was deprecated in the html4 and newer specs.

Matt, I like the ##hash marks for strikethru##, probably single hash marks would be sufficient, and the fact that the "#" is sometimes called a hash mark (IIRC) just adds to the intuitiveness.

• Hash marks might conflict with here-anchors. Currently anchors are limited to beginning of line only, but that does not necessarily have to be the case. -- JonathanCline - 28 Oct 2003
  • hmmm, be good not to step on anchors' toes. using double hashes would do that though (I think). -- MattWilkie - 28 Oct 2003

• strikethrough - do we really need that?
  • I use it when making small updates (a few words or a short sentence) that are major enough that I want people to know it's been changed, while minor enough not draw attention in a bolder manner. Of course if we had WordDiff I'd use that instead. Adding strike to twiki is easy, word-diff is hard. -- MattWilkie - 28 Oct 2003

...thought I'd better add that I'm not rabidly advocating for strike to be added. I'm personally comfortable enough with <s>strike</s>. I just thought that since we're discussing revamping the shorthand anyway I'd through it into the mix. (also see inline comments above)

Bear in mind that HTML4.0 defines <DEL> and <INS> and deprecates STRIKE. Personally I'm quite happy with these, and don't think we need a strikethrough syntax.
