A hold keybind for usercard pinning

[brian6932]

I'd like to for example hold CTRL and have the usercard pinned until I let go (specifically a keydown activation, and keyup deactivation). This way I can CTRL+LMB click a bunch of links without closing the usercard, or having to hunt for a small button in the top right corner of the usercard, and then hunt for it again to unpin. Basically emulating how a browser CTRL+LMB clicks/MMB clicks, the links open in new tabs instead of in the current one, causing no interruptions. Maybe this should also work with MMB clicks on links, like on a browser, or some bind that pre-opens a usercard in pinned mode.

So apparently this is due to FileProtocolHandler stealing focus on Windows and doesn't happen on every OS.
