How do I open an Excel form via Ctrl+[some other key]

Ctrl+W doesn't open your form, it opens the Watch Window. If you'd like to know more about Debugging then you might want to read my Debugging article. It's aimed at VB6 but it's valid for VBA.

Hello MartinLiss - Thanks for the info, but the instructor in the YouTube video says he's somehow assigned Ctrl+W to open his customized Watch Window in lieu of Excel's built-in Watch Window.  I didn't even know Excel HAD a watch window (I'm far from an expert, which is why I need help) so that's good to know.  Still, I like this cusomized Watch Window better than the standard one.

Can you post a picture of the customized watch window?

If you look about 8:25 into the video, Bill shows the ShowForm routine he uses to show the actual Watch Box form. You simply need to assign a shortcut key to that as saqibh already indicated.

Thanks for your info, rorya.  How do I assign a shortcut key to this routine?

Using the steps saqibh posted above. ;)

MartinLiss - Attached is a screen shot of my form.  Nobody answering me so far seems to understand that I can't figure out how to open any form in Excel - it's like it's a big secret - let alone assign this opening command to a key combination.

ssaqibh's answer is correct and here's more explanation.

Create this macro

Sub Macro1()
frmWB.Show
End Sub

Then do Tools|Macro|Macros and you will see the screen on the left. Select the new macro, click Options and you can assign a letter in the screen on the right.

Sorry I missed this solution before I continued seeking an answer.  Thanks to everyone for your help - it works perfectly!
