kglr's very useful trophy from the land of undocumented functions needs to be recorded. Suppose you have the following plot: Plot[Sin[2 Pi t], {t, 0, 1}, ImageSize -> Tiny] Then you can just cut and paste {100, 54} Note, however, that Predictions`getImageSize actually reports ImageSize plus ImageMargins, as shown in the listing below. ...

If you want to see when the notebook was last changed you could also use the information that is collected by the "Notebook History" functionality (of course only when you did not disable that functionality in the Advanced tab of the preferences). The following creates a cell which automatically keeps track of any change times, whether or not they have been ...

I was right using ExpandSelection twice does the trick, but not the prettiest answer, but anyway, just add this to MenuSetup.tr: MenuItem["Google", FrontEndExecute[{ FrontEndTokenExecute["ExpandSelection"], FrontEndTokenExecute["ExpandSelection"], KernelExecute[ $myContent = FrontEndExecute[FrontEnd`NotebookRead[FrontEnd`InputNotebook[]]]; ...

First, it hasn't been pointed out yet that the Notation package has the command AddInputAlias which is in principle designed to do what this question requires. There is even a palette for it. However, if you want to add several aliases all at once, the manual approach of the Notation package is inconvenient. One way to automate the creation of shortcuts is ...

I taught a blind student at our Uni a 1st year Maths module. We used his MacBook Air and he had a hardware device that rendered mac output as braille. We found that the key to communicating mathematics was a simplified form of LaTeX - which the student picked up very quickly. This, combined with Mathematica's LaTeX facility proved very successful.

I will try to add a more general function later, meanwhile you can use this procedure: Module[{cells, data}, cells = Cells[CellStyle -> "Section"]; data = ( SelectionMove[#, All, CellGroup, AutoScroll -> False]; NotebookRead[EvaluationNotebook[]] ) & /@ SortBy[cells, First@NotebookRead[#] &]; Do[ ...

Yes, with a bit of effort it is possible to construct such a package. My package Shortcuts, inspired by various questions and answers on this site over the years, can be installed in less than a minute from within a fresh notebook in Mathematica 9 or 10, on Windows, MacOSX or Linux by this Get@"http://goo.gl/aAxplX" or ...

Following up on my comment, and depending on the exact option whose value you are trying to unset, it may work to set the value of that option to Inherited. In fact, the documentation states that when you set a value to Inherited, "If no explicit setting is given at any level, then a built-in default value is used" (from the second bullet point in the ...

No, not possible at this time. While certain parts of the functionality can be upgraded by downloading paclet updates, a new version will contain changes to the kernel and frontend binaries, libraries and other system resources. The best way to upgrade is to run the installer. Another approach, if the newer version is already installed somewhere, could be ...
