Alt+Shift+F10 only works for the smart tags — double underline in Word, lightning bolt in Excel.

What you’re using is the “shortcut menu” or “context menu,” which we covered previously:

I find, though, that the alt-shift-f10 doesn’t work for me, but shift-f10 does. Anyone else? This was tested on Word 2007.

BTW, the same tip works when using Firefox and you get a spelling error indicated while filling in a text area. It would also work on the desktop, when you want to right-click to change screen resolution, or on a browser page when you want to access the menu that lets you see the HTML source for a web page, etc.

Finally, there’s yet another key–a single keystroke–to effect all the above. For those with a “windows keyboard” (where you have the “windows” key down next to the left Alt key, typically), you may notice another curious key, which has a picture of a menu with an arrow on it. On mine it’s next to the PrntScrn key. Called by some the “context key”, it’s used for the same thing as discussed in this tip: to pull up the context menu for wherever the cursor is currently located.

Hope that’s helpful. Keep up the good work!
