Good idea, @Bonobo! I particularly like your tip about taking a screenshot to the clipboard by holding down the Control key while taking the screenshot (it should work with Cmd-Shift-3, Cmd-Shift-4, and Cmd-Shift-5; please don’t post full-screen screenshots unless they’re necessary, though, because they’ll be too small to read) and then pasting directly into a forum post.
Also, with URLs, remember that if you put a URL on a line by itself, you’ll get a onebox preview. If you don’t want that, put a space in front of it, which might turn it into either a URL or just the title of the page. If you really want a URL, enclose it in < > brackets. I find the latter is helpful on another forum where the oneboxes and titles don’t work super well for things like Google Docs, Zoom, and Doodle links.
I don’t think it works with cmd-shift-5, because that version of the screenshot tool brings up an interface where you can select the destination from a menu (and the clipboard is one of the options):
Huh, interesting. Is this as you click Capture that you hold down the Control key? I tried Ctrl-Cmd-Shift-5 and nothing happened. And if you have selected save to a file or open in preview, does it do that as well as copying to the clipboard? (Not being lazy, I’m not at my Mac at the moment.)
