I am wondering if someone can help me to craft a custom command for Dragon or for Knowbrainer that would take a sentence and capitalize it and bold it. 

I would like to be able to highlight a sentence and issue one command that would do this. 

Thanks. 

This fast DVC HeardWord command should work. Simply import it into your Dragon® Command Browser (I attached it):

HeardWord "select","line"

HeardWord "\cap","that"

HeardWord "bold","that"

Needless to say, when you utter this command your cursor should be in the line you want to capitalize and bold. And of course this command will only work with (RichText) applications that support formatting (like DragonPad, WordPad, DB Advanced etc.).

Nice, works perfectly. Thanks. 

If you're OK with a custom command working only in Word, try this. This Advanced Scripting command should run almost instantly. You won't need to select the sentence, as the command does it for you.

Sub Main ()
With Selection
    .Expand Unit:=wdSentence
    .Font.Bold = True
End With

    HeardWord "\cap", "that"
End Sub

You'll need to set a reference for this command to "Microsoft Word XX.0 Object Library (Y.Z)"

The values of X, Y, and Z vary with different versions of Word.

(Edit: I updated the code because the original code I posted didn't quite work!)
