If I’ve got a big array displayed in Mathematica, is there a way for me to select a particular location on the screen and have Mathematica tell me “You’ve selected the entry in row 137 and column 92” (or whatever)?
I don’t want to painstakingly count rows or columns to do this myself.
The best kludge I’ve found so far is to select the part of the row or column up to the entry in question, copy that, paste it elsewhere as a list, and then determine the length of that list. But this seems needlessly roundabout, and it’s annoying to do when I want to determine the location of not just one entry but several of them in succession.
Is there a better way?
(For that matter, is there a way to tell Mathematica “Display the matrix with the entry in row 137 and column 92 highlighted”?)
