Not easily. If you really wanted I think it might work to use a customized icon font that replaces the glyph for
- with a checkbox glyph. You would need to:
run[link^="button"] in the stylesheet ... that's will target the leading dash.
Apply a custom "icon font" that you've created to that link:
font-family: "custom icon font name that's installed on your system";
More on what an icon font is can be found here:
Note, I don't think any existing icon font will work... you'll need to craft your own (using a font editor tool) that specifically replaces the
- glyph with a checkbox glyph. I don't think the font that you create really needs to have any other glyphs then for the
- since you'll only be using that font in the section that has the dash. TaskPaper will still think it's a dash, it will just look like a checkbox in the text view.
Also note, this is a big hack. I think it will work, but might run into some trouble that I'm not thinking about.
