TextClipboardType is an option for cells that specifies how Edit \[FilledRightTriangle] Copy treats a cell when converting it for the system's textual clipboard.

TracePrint[expr] prints all expressions used in the evaluation of expr. TracePrint[expr, form] includes only those expressions which match form. TracePrint[expr, s] includes ...

TrackedSymbols is an option to Refresh, Manipulate, and related functions that specifies which symbols should trigger updates when their values are changed.

Unevaluated[expr] represents the unevaluated form of expr when it appears as the argument to a function.

Verbatim[expr] represents expr in pattern matching, requiring that expr be matched exactly as it appears, with no substitutions for blanks or other transformations.

VertexAdd[g, v] makes a graph by adding the vertex v to the graph g.VertexAdd[g, {v_1, v_2, ...}] adds a collection of vertices to g.

VertexDelete[g, v] makes a graph by deleting the vertex \[Nu] and all edges connected to v from the graph g.VertexDelete[g, {v_1, v_2, ...}] deletes a collection of vertices ...
