Single dot textual form

Question

How do I render a letter with a single dot above it?

I see \[DoubleDot] and \[TripleDot] are readily available, but what about a single dot?

Specifically I am after Q dot, which is used in thermodynamics. If it helps, here is some background on Unicode and Q dot.

Answer 1

Use OverDot

ref/OverDot in the documentation (but one of those cases where you need to know what you want in order to be able to enter it)

OverDot[Q]

Answer 2

In addition to Mike's post two things you can do:

• Type "Q" then press Ctrl+& and then type "." to enter with a shortcut.

• Use palette - there are actually a few you can use. For example go menu Palette >> Other >> Basic Math Input . This will bring a neat concise palette of frequently used input forms. Bottom left corner has what you need.

Little, but convenient things, - I use it often myself ;)
