Global shortcut to bring up fman

Hello,
I would like to request a possibility to bring fman to front, with a global hotkey,

This was already briefly covered by issue #144 but the OP's focus was on being able to minimise fman to system tray (any OS). This is nice to have, but then requires a user to use mice, to click fman out of the system tray. The OP in above issue mentioned Global Shortcut to bring it up, but I don't think this requirement was captured (and I don't believe it these two functionalities need to be merged).

So here is my case: have a global shortcut to 'bring up' from tray OR 'un-minimise' from taskbar.

I already use "alt+space" to bring up my keystroke launcher (autostarts)
I will hit "alt+r" to bring up resoph notes (which is synced notepad and is awesome, also autostarts)

I would love to be able to press alt+f (configurable?) to bring up fman from wherever it is.

Since the fman seems to be aimed at 'keyboard users', the global shortcut will significantly boost convenience.

cheers, grand

Review issue #144 and the existing fman window and system-tray activation paths first. Determine how a configurable global shortcut could bring fman forward from the tray or taskbar across supported operating systems, then verify that the shortcut works while fman is backgrounded and does not conflict with normal window behavior.
