Questions related to the Mathematica front-end (graphical user interface).

Mathematica is divided into two pieces: the kernel which performs all the calculations and the front-end with which the user interacts. The front-end is responsible for displaying and styling the notebook interface, and launching the kernel when a calculation needs to be performed.

Since the front-end is a vast system, please consider using some more specific tags too. Use this tag (with the appropriate specific tag) for questions on customizing the front-end options or modifying *.tr files (), creating keyboard shortcuts (), creating stylesheets (), syntax coloring (), etc. Questions relating to nootebooks, their structure and behaviour, dialog and normal notebook windows should use the tag . Questions relating to palettes should use the tag .
