Markdown: open preview to the side should be Ctrl/Cmd click, not Alt

Refs: #7945

At least that would be consistent with other places where we open to the side and matches old behaviour.

Yeah, I don't like ctrl/cmd but I take the consistency point...

Actually, I take that back ;-) The Alt modifier is a menu item modifier and not an argument to the command. Since, it's the alternative action for a menu item I think the alt-key is a good choice. In that respect it's different from ctrl/cmd click on tree items which we lend from hyperlinks in browsers. The point of Alt is to show an alternative less common version of a menu.

@bgashler1 I know you wanted to join in this discussion. Please go ahead ;-)

Also, while we only honour Cmd/Ctrl at the time of the click, Alt is being honoured while being over the menu item.

Fyi, using Cmd/Ctrl in trees is also not a good idea because when multi select is on, Cmd/Ctrl is reserved for multi select.

So, having Alt everywhere is maybe a good idea, but will break existing assumptions.

Thanks for including me in. I think this would be good to discuss in UX meeting. I personally don't think it's very discoverable to use an Alt key to change a command. It's not a bad idea by any means, but I think it's unlikely many people will ever know about it.

[bpasero]

I do think it is common for Mac users but not for Linux/Windows users.

After the discussion I opt to leave this with Alt

let's leave it by alt
