OverDot
Details
- OverDot[expr] can be entered using
and a period. - OverDot[expr] remains unchanged by evaluation.
- Allowed values for the number n of dots are 1, 2 and 3.
- OverDot[expr,2] can be entered using
and \[DoubleDot], while OverDot[expr,3] can be entered using 
and \[TripleDot].

OverDot[expr] and OverDot[expr,1] both display with a single dot:
{OverDot[v], OverDot[v, 1]}Display v with two dots above:
OverDot[v, 2]Type 
and then \[DoubleDot] to enter directly:
Overscript[v, ¨]//InputFormDisplay v with three dots above:
OverDot[v, 3]Type 
and then \[TripleDot] to enter directly:
Overscript[v, ]//InputFormProperties & Relations (2)
OverDot is effectively a special case of Overscript:
{OverDot[x], Overscript[x, RawBoxes["."]]}If the output is used as input, both expressions standardize to OverDot:
{Overscript[x, .], Overscript[x, .]}//InputFormOverDot[expr,2] uses \[DoubleDot]:
MakeBoxes[OverDot[x, 2]]//FullFormOverDot[expr,3] uses \[TripleDot]:
MakeBoxes[OverDot[x, 3]]//FullFormText
