Perspective/Orthographic toggle without numpad (or emulating)

In my work I tend to switch a lot between perspective and orthographic view. Normally this is easy with Numpad 5. I've been trying to do more work on the go with a keyboard that doesn't have a numeric keypad. I've tried emulating the numpad, but this also overrides the selection mode when editing, along with other default keymap in 2.8.

The recent keymap changes have done a pretty great job at trying to make desktop and laptop feel like similar experiences. The tilde pie menu for view switching has proved to be pretty fast, but there's no option for perspective switching. Maybe adding that to the menu, or another default hotkey would be an option?

I've tried some of the ported pie menu add-ons, which have this option in a sub-level of the pie menu which overrides the Q favorites menu and you can't trigger it by releasing the hotkey.
