My Outlook is set to “Hide When Minimized” (see this). Is there a keyboard shortcut key to “unhide” it instead of going to that icon and right clicking it and selecting “Open Outlook”? Or at least, is there a fast way to do that with a keyboard?
Edit: It looks like there is no shorcut (yet). The best way (so far) to do it with the keyboard:
Win + B - Focus on the notification area
Right Arrow to get to Outlook icon
Enter to restore
You can actually do just that, without much trouble at all, and with a single shortcut key. I've written an article covering how to do it:
Keyboard Ninja: Create a Hotkey to Switch to Your Open Outlook Window
In short, you'll just tack /recycle to the end of a shortcut, and add a shortcut key.
Double-clicking on the Outlook tray icon will restore it or bring it to the front. (Not keyboard, but still faster than right-clicking and selecting Open Outlook.)
I don't think so, not directly -- the problem is you can't send shortcuts to applications which do not currently have focus, so you'd have to click the system tray icon to give it focus, and since you've done that, you might as well click it again to bring it up.
For keyboard-based shortcut, you can Alt + Tab (or in Vista/Aero anyways, Windows + Tab) to spin through the current open or minimized applications via keyboard and then select the one you want, which will pop up the minimized window. Neither seems to show "hidden" applications, though.
You can assign a keyboard shortcut to Outlook by right-clicking it's icon in the Start menu and selecting 'Properties'. Then when you use this shortcut Outlook will restore from the system tray (or start if it's not already running).
