Staff View: Is there a keyboard symbol for the "natural" sign?

Well, the title says it all. I've noticed, with some displeasure, that Sonar is somewhat lackadaisical when it comes to displaying the correct accidentals in Staff View. Probably the worst offense, which I see consistently, is when a note has been sharped or flatted, and then later in that same measure, a natural of that note appears. If the notes are very close to each other, then Sonar will add the natural symbol, but if the natural note is located further out in the measure, Sonar almost never adds the natural symbol. I have no idea why it chooses to get lazy like this, but I'd like to be able to input the natural symbol when these cases arise.
 
So, those of you who are experts at Sonar's Staff View -- such that it is -- care to enlighten me?

I don't want to mess with all that. I just want to be able to type a symbol. I should just do process of elimination. Try all the keys, both regular and shifted. Except "b" and "#" of course. If it's possible, one of them will do it.

Hi, mwmcbroom! I guess you could also right click the note and change its name on the note properties dialog box. You would change Cb4 by B3, for example.
This also could be done with the event inspector, but it doesn't work well for enharmonic notes.

Hooboy. Guess I'll just write 'em in on the printouts.

I already did that. Key of G. Problem is an occasional C# appears early in some measures, then a C natural late in the same measures, but with no natural sign . . . as I've sorta explained already.

Start by knowing that I know nothing much about notation.

But if you are in the key of g where c would be natural, wouldn't you just display c anyway (without a natural symbol) ? I guess I understand why within a measure that had an accidental followed by the natural form you would show the symbols for both, but I thought you only generally displayed a symbol at all when it was an exception to the key.

When something is sharpened, it stays sharpened for the rest of the bar. In other words, you show the sharp for the first occurrence, then every other occurrence of that note in the bar is assumed to be sharpened until you use a natural sign.
