May 28	comment	Strange setting in FormatValues[MakeExpression] @Sjoerd But this is not may only setting, and I think to make `\|<stuff>\|` to be recognized as input, this wouldn't suffice.
May 28	comment	Strange setting in FormatValues[MakeExpression] @Sjoerd I want e.g. to print `Abs[<stuff>]` as \|<stuff>\| enclosed in `\[LeftBracketingBar]` and `\[RightBraketinbar]` in StandardForm, and I use `MakeBoxes` and `MakeExpression` for this.
May 28	comment	Strange setting in FormatValues[MakeExpression] @Sjoerd To make some output "prettier", I use `FormatValues` and I inspect them to see if everything is correct. BTW it seems, that the entry above does no harm, but if I spot an error/warning I´m curious where it comes from.

May 22	comment	Is there a way to localize Off[some::message]? @celtschk I use this mainly in packages, where I don't want to suppress all messages, but only those I know to be harmless in this case.

May 9	comment	Extract current viewing parameters from a 3D view? @cormullion 1.) If you don't move, rotate, ... the grahphics with the mouse, the output will be an empty list. 2.) Yes, you have to Ctrl+Shilt+L the graphcs between the [ ]. The `ll` used in the definition will then be replaces by the graphic (which is a mathematica object like any other).

May 9	comment	How to find the smallest root @Artes Ok that is what we call a "weak" monotonic function.
May 9	comment	How to find the smallest root I'm a bit confused. For a monotonic, continuous, differentiable function F with supremum c all values F[t] are less then c. Or am I missing something? Could you show the definition of F?
