Is there a way to clear everything before starting in Mathematica?

Question

In MATLAB there is the function clear to delete all current variables. This is very useful if you start something totally new and don\'t want to get conflicts with earl

Answer 1

I recommend one of two methods:

1. Keyboard shortcut to Quit[] the kernel

There is a system file KeyEventTranslations.tr that you can edit to customize keyboard shortcuts. I, as others, have added Ctrl+Q to Quit[] the kernel, allowing for a rapid clearing of all sessions variables. For more information on setting this up, see:

• Customizing Mathematica shortcuts

2. Give the new Notebook a unique context

In Mathematica, the current $Context defines what Context unqualified symbol names belong to. By giving a new Notebook a unique Context, which is easily done through the Evaluation menu, the symbols used in that Notebook will not collide with unqualified symbols in other Notebooks. See the following question for more detailed information:
