Diacritical marks: How do I add a 'dot' above a letter?

The subject says it all. I'm trying to put a dot above a capital M. It's common physics notation for rate-of-change, and easy to do in LaTeX as \dot{M}. I can insert diacriticals such as accents and umlauts over letters using Alt combinations shown on the Keyboard Viewer or Character Palette, but I can't figure this one out!

This isn't an 'answer' as such, but I've just manufactured what you're looking for using AppleWorks > Drawing. Type in a capital M and then, in a separate text box, type Option-8. Park the latter over the former, just as you want it, and then Group the two objects. Using it in text-only may prove to be a problem, eg. I couldn't enter it here.

This will only work with apps that support unicode, but you can use the character palette. Look in the unicode section, under "Combining Diacritical Marks" or "Combining Marks" (codes 0300-036F). As the name implies, these are characters that can be combined with other characters to modify them. I don't know if it's the exact one you want, but there is one called "Combining dot above" (U0307) for example.

To use it, Type the letter you want to modify (eg. "M"), then immediately use the character palette to insert the "combinint dot above" character, and the dot should appear above the "M" (as opposed to beside it).

Alternatively, if the "Unicode Hex Input" keyboard layout is active (it can be enabled in "System Preferences" > "International" > "Input Menu"), type "M", then, while holding down the "option" key, type "\0307" (without the quotes).

If you were really motivated, it might also be possible to construct a custom keyboard layout to add the additional dead key for the dot symbol...

Look in the Character Palette (System Preferences, International) under Latin.

You clever eagle-eye you! May I just amend that to plain "Character Palette > European Scripts > Latin".
